Not so.  Better for you to read `man find` before posting.

The slow part of what he did is the "v".

Take out that "v" and it will go much much faster.

Charles, if you get tired of the issue, you could, instead of solving 
it, set up a local caching nameserver (I use bind).  You might also 
need to disable updates to /etc/resolv.conf as I did (Gnome's System -> 
Administration -> Network : Devices -> Edit : DHCP Settings : 
Automatically obtain... = unchecked).  I also made mine Immutable.  
With a local nameserver, /etc/resolv.conf should either list only 
"nameserver 127.0.0.1" or it should have no nameserver entries.

LMV2 boot from another Volume Group?

[Tony Nelson]

I have two hard drives I want to boot from, each with its own LVM2 
Volume Group.  I can boot from the one on the same drive as Grub, but 
not from the other one.  Apparantly, only Logical Volumes from the boot 
drive's Volume Group are detected before / is mounted (something about 
"activation", perhaps?).  Googling only shows how to detect Volume 
Groups and activate Logical Volumes after / is mounted.  I can't find 
any kernel LVM parameters that would affect this (and I'd need the LVM 
stuff built-in to the kernel, not as a module).

Can Linux use a Volume Group that isn't on Grub's boot volume?

Must I add a boot partition on the second disk and chainload to it?

This is wrong.  In order to use an LVM Logicial Volume, first a 
`vgscan` may be needed to make the Volume Groups known, and then the 
desired Logical Volumes must be Activated with `vgchange -ay`.  Only 
Available Logical Volumes can be mounted.

Either way (with suitable changes to grub.conf).


> Second question - do the two VGs have different names?

Yes.

Even when the boot drive is set in the BIOS to be the drive containing 
the Volume Group to use, VolGroup01, all Volume Groups are recognized, 
and then VolGroup00's volumes are activated.  I see that nash has 
started.  In the initrd, the nash script "init" contains the offending 
settings.  I suppose I need to use mkinitrd to fix this, so that 
VolGroup01 (and also VolGroup00 which contains the swap partition) is 
activated.

(I'm baffled as to why `grep -rI nash .` in the unpacked initrd would 
cause endless spew of RETURN characters into any active window, as if 
from the keyboard, making the computer unusuable and also hard to 
reboot.  "-rIl" spews something else, maybe spaces, not quite as hard 
to reboot.)

[solved] Re: LMV2 boot from another Volume Group?

[Tony Nelson]

I'm back now, with an updated system.  In order to copy a system to a 
new disk and Volume Group, one needs, along with a fresh install of 
Grub, a new initrd with info from the new updated /etc/fstab.  It's not 
necessarily an LVM issue.

All this was fine, as booting had started (kernel loaded, initrd 
loaded).

Doing `mkinitrd -f /boot/initrd- ` 
fixed the problem.  Note that mkinitrd trusts /etc/inittab, so that had 
better be right.

None of that had anything to do with the problem.  As I mentioned 
previously, nash had started (so Grub was well out of the picture) and 
then not all needed Logical Volumes were activated.  I'd heard of nash, 
but had never known quite where it was in the boot process.  I'd never 
looked into the initrd either.

Thank you for your efforts.

It could be the new kernel.  Try a previous kernel.  Press a key while 
Grub is starting during boot (just before the kernel is loaded), and, 
when the Grub menu appears, use the up/down arrow keys to select 
another kernel, and then press RETURN (or right-arrow) to boot.

Well, you're narrowing it down:  it's not the kernel.  Try booting 
without "rhgb" and "quiet", by getting to the Grub menu as above, and 
using Append ("a") to get to the kernel command line, and Backspace to 
delete those options (arrow keys to skip over stuff not to delete).  
You might see something informative when booting pauses.  Also, the 
Boot Log is back, sort of, in /var/log/boot.log.  It may not show 
anything from the proper time, though, as it covers service startup and 
not what happens in the initrd "init" nash script (which I just learned 
about).

Only the stock items need be preserved, possibly with (hard) links to 
the current version for files that are unchanged.  You could request 
that Fedora packagers do this in a post-install script, citing the "by 
design" from the bug above.

Fedora 11 lm_sensors on ASUS MB solved

[Tony Nelson]

In F9, lm_sensors worked, but in F11, it said "no sensors detected".  
Eventually I found



which showed that the lm_sensors developers had broken lm_sensors on 
purpose for (all?) ASUS motherboards, with an unfinished "improvement".

To get lm_sensors working again, add the following to the Grub kernel 
boot line:

acpi_enforce_resources=lax

This returns ACPI enforcement to it's previous unchecked state, which 
is still used for all other motherboard manufacturers, according to the 
thread linked above.

Also ensure that the needed modules are loaded, which may require the 
new syntax in /etc/sysconfig/lm_sensors.

Fedora 11 does display suspend work for you: CRT vs. LCD

[Tony Nelson]

On Fedora 11, does your display suspend after the screensaver activates 
(assuming that you have asked it to suspend)?  If you know whether it 
does or doesn't, please reply, and say whether your display is a CRT or 
LCD.  I'm trying to get more information before filing a bug.

(I did create a new test user and try from there, without success.)

I think that LCD / Laptop users mostly care about dimming / blanking 
and not about suspending the display, but as a CRT user, I'd like to 
save the power.

On Fedora 9, the screensaver (and gnome-power-manager) blanked my 
screen and then put it in the low-power suspend mode.  Fedora 11 dims 
my screen, but does not put the display into suspend mode, so it still 
draws full power.  Diff'ing the code for F9 and F11, and viewing 
output from `gnome-power-manager --verbose`, I see no way for the 
current G-P-M to suspend the display, as the code that called DPMS to 
do so has been removed.  G-P-M seems oriented to LCD displays and 
Laptops now, so this may not have been noticed.

That pretty well proves that it can work on a CRT.  Thank you.

If you feel up to it, could you kill your running gnome-power-manager 
and start a new one in a terminal with `gnome-power-manager --verbose`, 
and let the display sleep and wake up, and send the output directly to 
me?  (Kill the new G-P-M with Ctl-C.  Something started a new one for 
me, possibly switching users, but it might be better to start it 
yourself with `gnome-power-manager &'.)  Note that there's some risk in 
all this, that you might lose control of your display.  The output 
might show me what is different about our systems, from G-P-M's point 
of view.

I wonder if it's a ATI Radeon or ASUS MB issue.  Both are old.

It only needs to be a module, but then it must be present in your

OK.

I just leave them there until my /boot gets full.  If they're from 
RPMs, I do a `yum remove kernel-`, otherwise I just `rm *-
`.

Probably.  I don't use grubby (if needed, I write my own grub stanza).  
You may have to use the source to find out.

When yum gets weird I `yum clean metadata` and usually that fixes it.

I'm a sloppy person, so I set up an rsync-based solution derived from a 
script I snagged through googling.  It keeps 4-hourly, daily, 4 weekly, 
and several monthly rotating backups of the directories I list.  Let me 
know if you want it.  Sometime I'll clean it up some more and put it on 
my web site.

Now, don't be hasty, grubby does do several things (whatever they are). 
You could peruse the source to see what grubby is up to, without really 
having to understand it.  Also, you can run it under gdb and get a 
backtrace, without really having to understand it, though you should 
install the debuginfo beforehand with `debuginfo-install grubby`.

I use an Athlon 1.2GHz 768MiB machine, ATI Radeon 7000/VE, F11 EXT4, 
and it's fine for speed.  Others report success with much slower CPUs.

The only really slow thing was the SELinux relabel on first (and 
second) boot.  I haven't felt any other slowness after my upgrade from 
F9, or today's separate installation from the F11 Live CD.

So, look for some other problem.  Bad Xorg video mode in /var/log/
Xorg.0.log?  `top` shows heavy load?  (I keep the Gnome System Monitor 
applet in my top panel for a quick overview.)

Or this:  look at /etc/event.d/serial.  I don't know from upstart, but 
it seems that it should be automatic if you specify a serial console in 
the kernel boot options.

It's the kernel.  2.6.29.4-167.fc11.i586 suspend works.  
2.6.29.6-213.fc11.i586 no suspend.  I'll narrow it down more later with 
packages from koji.

I still don't know what is actually calling DPMS to suspend the 
display, but I do have it working with the original kernel from the 
DVD.

I wish I'd tried the kernel sooner.

Is this so you back up conf files that aren't stored in /etc, or 
because you can't afford the space for a full copy of /etc?

OK, so you want to rewrite those sectors, but don't know where they 
are.  `fsck` is unlikely to help, as most sectors are not holding the 
filesystem metadata, but actual data or are free.  (As your sectors 
are known bad, they probably are not free.)

There are various rescue tools.  You could use `dd` on every file 
(from `find`, perhaps), and note where it complains.  Some files might
be fixable, others might be recoverable or replaceable, and some will 
just be damaged.  You could use `badblocks` on the disk, and just nuke 
the offending sectors, accepting the damage to unknown files.

I see that Auto Offline Data Collection is enabled.  Usually the 
"every-four-hour" scan will recover sectors as they go bad.  It is a 
bad sign that some have accumulated, if it happened when you had Auto 
Offline Data Collection enabled.

That might be tricky.  rsync has the "--files-from=FILE" option, but 
geordy_backup doesn't bother, it just lists the files (actually only
directories) in the script.  The "sloppy" principle says that I won't 
list all the files I need, but that entire directories are likely to 
be enough.

Re: [Solved] Re: Fedora 11 does display suspend work for you: CRT vs. LCD

[Tony Nelson]

Current F11 failing to Suspend the display when the screensaver 
(actually Gnome Power Manager) blanks the screen is a bug in Kernel 
Mode Setting (KMS).  The problem can be demonstrated with xset:

xset dpms force suspend ; sleep 10 ; xset dpms force on

Disabling KMS with "nomodeset" on the kernel command line allows 
2.6.29.5 and up kernels to Suspend the display just as 2.6.29.4 
kernels can with or without KMS.

Bugzilla <https://bugzilla.redhat.com/show_bug.cgi?id=515316>

The low-level formatters I have used are all floppy-based, mostly using 
some free version of DOS (FWIW).  Find the drive manufacturer's 
utilities disk, copy it to a floppy (or whatever), and boot it.

On the drives I've low-level formatted, the process eliminates sector 
remapping, but does introduce "gaps" in the good sectors.  The capacity 
might be reduced, but mostly it just works into the spare blocks area, 
reducint it in size.

If, after such a low-level format, you still accumulate bad blocks, you 
should give up on that disk.

To reduce the amount of data loss as blocks go bad, use smartctl to 
enable Automatic Offline Data Collection.  It will scan the disk "every 
four hours", which gives the disk a good chance to catch blocks as they 
go bad but are still recoverable.

This is how PA volume controls work, and appears to be By Design.  They 
have a logorythmic scale with about 100 dB range.  A mouse hover over 
the closed volume control may show the attenuation.  I think they are 
all intended to be left at or near maximum, and you are expected to 
control the actual volume with some other volume knob, say on your 
external amplifier.  This is problematic for those who aren't using an 
external amplifier, but that isn't PA's target audience.

Updating Firefox or anything else while it is running won't bother yum. 
It may (and does) bother Firefox, when it tries to open a file that 
isn't there anymore, but all files it has open still exist, though 
without names, after they have been replaced or deleted.  That's how 
*nix filesystems work.

I restart Firefox after updating it.

If you just want to keep using the connection while a download is 
taking place, you might benefit from traffic shaping, and possibly from 
the Wonder Shaper (Google for it).

yum-presto is also good, but it only reduced the initial update from my 
own F9 to F11 uprade by about 1/3.  It only looks for one level of 
delta-RPM, so after there have been multiple updates there isn't a 
delta path.

Yum from the command line gives good feedback on what and how much, and 
reasonable feedback on how long.  (I don't use Packagekit's applet, so 
I don't know about it.)

Re: low-level formatter for linux

One thing is that each of those blocks requires a long seek to the 
replacement block.  After the drive manufacturer's low-level format, 
all the blocks are in order, with only short skips past the bad blocks, 
and possibly a slight reduction in the size of the spare blocks area.

Modern drives (last 8 or so years) have good support for automatic 
remapping of bad blocks, because bad blocks are expected at the 
magnetic domain sizes being used.  With Automatic Offline Testing 
enabled, most bad blocks are remapped before complete failure and 
without data loss.

I've been using one "dying" drive for 7 more years now (with one low-
level format), and another for about 4 more years.  I'm using a drive
I found in a snowbank, without difficulty and without bad sectors.  I 
have SMART monitoring enabled, so email will be sent to root if SMART 
gets unhappy, and Auto Offline Data Collection enabled, so blocks are  
being salvaged as they go bad.  I'm /not/ using that panicky Palimpsest 
(gnome-disk-utility applet), so I don't get spurious warnings (moderate 
numbers of reallocated sectors are not bad -- though offline-
uncorrectable and pending sectors are bad).

Supposedly this only affects ASUS motherboards, and then only 
lm_sensors.  Currently, its only function is to prevent lm_sensors from 
working on ASUS motherboards.  Someday it may do more.

No, even though ASUS does not document their hardware, it isn't for 
anything they added.  It is a half-baked attempt to require that only 
one driver use a piece of hardware.  Currently it is only enabled for 
ASUS motherboards, and is only used by lm_sensors.  See, for example, 
this thread on LKML:

If you move your "best" download to the torrent download destination, 
bittorrent will just copy the parts that aren't correct.  It will 
usually be much faster than starting from scratch.

If, from X, `xset dpms force suspend ; sleep 10 ; xset dpms force on` 
doesn't suspend your display, try booting without Kernel Modesetting 
by appending "nomodeset" to the kernel command line.

If you don't need suspend, perhaps you can disable it?  Though I'm not 
sure if that will make it stop.

If you can't solve the problem, and you don't need fancy Power 
Management services, you can `yum remove gnome-power-manager`.  I did 
that and also removed gnome-screensaver, replacing both with 
xscreensaver.  I don't use suspend or hibernate, but I do want the 
display to sleep, and, as a bonus, I get better looking screensavers.  
I did lose the ability to switch users without first unlocking the 
screen.

No, but I do use rsync.  It appears that the VM is running out of 
memory.  You don't give your rsync command, but I suspect that you are 
using an option that requires extra memory, such as "-H" (preserve hard 
links), or possibly not using "-r" (recursive) for the new incremental 
scan that doesn't need to load all the directory info into memory.

Rsync can use a lot of memory if some file being tranfered is huge.  It 
will use less memory for the same amount of data in smaller files.

You don't say quite what you're doing, but if you are just copying the 
data (that is, there isn't a destination that is nearly the same), you 
might not need to use rsync at all, but some other file copy utility 
instead, such as scp (slow but secure and reliable).  Umm, when I want 
to copy a few GiB from a VM to the host, I now shut down the VM and 
mount its root locally, and do a normal copy.

I don't see anything that would use extra memory, though usually the

I think that is just a side effect of your VM running out of memory.  
Running out of memory is what you need to fix.  Did the Xen VMs have 
the more memory?

Do you have updates-testing enabled?  F11 doesn't include 2.6.30

`rpm -e`is fine, but yum will remove dependencies as well:

yum remove kernel\*-2.6.30\*

If it wants to remove the world, say "no" and look at the dependencies.

Thanks.  So it's not just a "power of 2" issue.

I wonder if it is related to the size of an "erase" block (which I read 
are usually 64K, 128K, or 256K)?  When writing is slow, there may be 
lots of read/alter/rewrites happening, with extra wear on the flash.

I also see font rendering artifacts, mostly in Firefox, but in other 
apps as well.  I blame the video driver, possibly the EXA acceleration, 
though I haven't tried XAA yet (per `man radeon`).  I have an old ATI 
Radeon RV100 QY [Radeon 7000/VE] rev 0.  It could be that your lockups 
have the same cause.

That suggests that system-config-language could not find any default.

I think that the "commented out line" should be made like the one from 
F9, as currently no default LANG is being set.  I could imagine such a
thing having come from Rawhide at one time.  Check for any .rpmnew 
files like /etc/sysconfig/i18n.rpmnew.

You might first try setting the mouse Sensitivity and Pointer Speed as 
low as they go, so that moving the mouse across the screen will require 
moving your hand rather than flexing your wrist.

Note that the injury one gets from repeatedly flexing your wrist is not 
to the carpal tunnels.

Injury to the carpal tunnels can result from extended periods of typing 
with the wrists bent up to type on a low keyboard.  Raising the 
keyboard to upper-chest level will prevent such bad wrist positioning, 
as will most "standing stations".  A "wrist rest" also straightens the 
wrists, but applies pressure to the carpal tunnels, adding to their 
irritation.

Because the GRUB stanza you copied to boot F11 says:

root=UUID=7ba6f364-68c2-4dad-a54e-18c3464b0eb5

That is, it says root is identified by its UUID.

Perhaps that is not the correct name, or your "root" line is wrong.  It 
is also possible that the UUID was changed when you reinstalled (though 
it should not change unless you reformatted the drive).

`info grub` shows that Error 17 is "Cannot mount selected partition", 
which means that it can't handle the "root (hd1,0)" line.  Check that 
"(hd1,0)" is the /boot partition for F11, containing the vmlinuz and 
initrd files for F11, and that it is an EXT2/3 partition.

You might have an easier time just chainloading to the F11 GRUB.  Use a 
stanza like the "Other" stanza, but for "(hd1,0)" (if that is the 
correct partition).

1) Wait.  If the disk is going bad, it will fail.

2) Run as root `smartctl -A /dev/sdx` (for each sdx) and look at the 
"WHEN_FAILED" column; it will be "-" if not failed.

3) Run as root `smartctl -a /dev/sdx` (for each sdx) and look at the 
whole output.

4) Run as root `smartctl -t long /dev/sdx` (for each sdx) and wait 
until the time the test should finish, then view the results with 
`smartctl -l selftest /dev/sdx` (for each sdx) or `smartctl -a /dev/
sdx` (for each sdx).

See `man smartctl`.

Note that the new disk health monitoring tool "palimpsest" in package 
gnome-disk-utility is panicky and not to be trusted, unless you like 
buying lots of hard drives.  It doesn't just look at "WHEN_FAILED", but 
has its own criteria such as nonzero Reallocated_Event_Count, which is 
fairly normal for a modern drive that has been in use for a while.  A 
nonzero Current_Pending_Sector or Offline_Uncorrectable are bad, as 
they mean data loss, though not general drive failure.  I recommend 
enabling Automatic Offline Testing with `smartctl -o on /dev/sdx` (for 
each sdx), which will do a surface scan every few hours, giving the
best chance to repair or recover any sectors that are going bad.

FWIW, here tzdata was updated today, so perhaps, if you have automatic

And if you want to get rid of it, remove the "SubSystem" line in the

Here `MAKEDEV -n fd0` said all the device nodes would have group 
"floppy".  If that is what your device nodes show, then adding the user 
to the "floppy" group should work.

How about you?  That's what I'm doing, but only for one machine.  The 
Fedora bind RPM is set up as a caching-nameserver, so just let it do 
its thing (unless your ISP blocks outbound port 53 traffic).  You do 
need to set your server's /etc/resolv.conf to 127.0.0.1, and for your 
other machines, the server's IP, and in /etc/named.conf, add the 
server's IP to the listen-on line, and add your local subnet to the 
allow-query and allow-query-cache lines (I hope I know what I'm talking 
about).  There are some hints in /usr/share/doc/bind-*/sample/etc/
named.conf.

Well, yes, it's the one you have with debuginfo installed (`debuginfo-
install firefox`, 17 packages and 227 MB here, if I'd done it).  Then 
attach to the running firefox with gdb (use `ps -ef | grep firefox` to 
find the real firefox and its pid) with `gdb path/to/firefox the_pid`,
and wait for trouble.

I'd expect that firefox is already able to report its crashes, and you 
have done so, and you just want the information for yourself.

Package "bind" provides caching-nameserver nowadays.

What is the output of `route` on that system?  I expect that there is 
no route to the destination address.  "route" can also be used to add a 
route with a command like `route add xx.xx.xx.xx dev eth0`, see `man 
route`.

I expect that the problem now is the route, but how are the two 
computers connected?  If they both connect to a router / switch and can 
both use the Internet, then they should already see each other 
(usually).  If they're just cabled together, well, that might not be 
working.

Try booting with the "nomodeset" kernel parameter, to disable Kernel

I think the problem is that PROMPT_COMMAND is setting it each command, 
after you set it.  Either unset PROMPT_COMMAND or change it to do what 
you want.

If `xset dpms force suspend ; sleep 10 ; xset dpms force on` doesn't

Cable?  Either a better cable, or improve its routing, or just crumple 
it so it can't cozy up to anything else, or simply unplug and replug 
it?  Also, what's on the power connector?  Unplug and replug that one 
too.

Replacing the drive can be done by adding a new drive to the Volume 
Group and using pvmove (not that I've done it).

File a bug against your video driver or just against xorg.  Fixing "it" 
(Kernel Mode Setting) yourself is not feasible.  Use the workaround you 
have now.

Or you may not have Palimpsest (gnome-disk-utility) installed or 
running.  I got it on a new install of F11-Live, but not on an upgrade 
from F9.

No.  Nor for non-RAID either.  It doesn't "fix" Reallocated_Event_Count
-- rather, its purpose is to make Reallocated_Event_Count go up faster, 
in that as soon as a sector starts to go bad it will be reallocated if 
readable, and the sooner the more likely it is possible.  A non-zero 
Reallocated_Event_Count is not a problem.  Whatever says it is a 
problem is the real problem.  Fix that instead.

Non-zero Current_Pending_Sector is a problem, but RAID should be fixing 
that already.  I don't know, but I think that enabling Automatic 
Offline Testing should cause any uncorrectable sectors to be noticed 
and fixed sooner by RAID.

Automatic Offline Testing must be enabled on an actual ATA hard disk, 
so no fake disk such as dm or md.  See `man smartctl`.

Bash should be OK if Pathname Expansion is used instead of the more 
general Brace Expansion:

$ for w in [[:upper:]][[:upper:]][[:upper:]][[:upper:]][[:upper:]]
[[:upper:]][[:upper:]][[:upper:]] ; do echo $w ; done

However, if there are no matches, the match string will be tried unless 
the shell options failglob is unset and nullglob is set:

$ ( shopt -s nullglob ; shopt -u failglob ; for w in [[:upper:]]
[[:upper:]][[:upper:]][[:upper:]][[:upper:]][[:upper:]][[:upper:]]
[[:upper:]] ; do echo $w ; done )

(Sorry for the wrapping.)

WAG:  The RewriteRule doesn't actually rewrite anything.  Perhaps

It is likely that the disk has one or more bad blocks.  Use
`smartctl -a /dev/sdx` to see all the data (or -A to see only the 
attributes) and look at the raw values of Current_Pending_Sector and 
Reallocated_Event_Count.  The first reflects unfixed problems, and the 
second fixed problems.  If both numbers are low, I would just keep 
using the drive, though I would first do a long test with `smartctl -t 
long /dev/sdx` (wait until the indicated time and then do a `smartctl -
a /dev/sdx` to see what happened) and then enabled Automatic Offline 
Testing with `smartctl -o on /dev/sdx` (this will help keep up with 
sectors as they go bad, without unnecessary data loss).

A program such as ddrescue (`yum install ddrescue`, `info ddrescue`) 
may help to salvage the damaged file(s).

13 is a bit high considering that it reflects only the bad blocks that 
have been noticed, but it could still be from a single bad area.  The 
results from the long test will help decide.

That won't happen, as the drive will use a good block to replace the 
bad block when it is written to.  The real question is how many more 
blocks will go bad, and the long test should give a hint about that.

Yes, it seems to have given up at 12 blocks.  The trick is to find what 
files those are and deal with them, so that the test can be run again 
to see what else it might find.  Once the damaged files are found, you 
can decide whether to recover them, restore them from backup or some 
other source, or just delete them.

I don't know of anything specifically intended to find the damaged 
files.  e2fsck will map out bad blocks, but doesn't (AFAIK) tell one 
which files are damaged.  I think tar can be used to find such files, 
but I'm not sure.  As you know of one file that has a problem, I 
suggest trying this command on the directory which contains that file:

# tar -cf - --ignore-failed-read /path/to/bad/file's/dir >/dev/null

Possibly -v will also be needed.  In that case, the full scan should 
probably write the messages to a file:

# tar -cvf - --ignore-failed-read --one-file-system / >/dev/null \
  2>/some/other/volume/tarfiles.txt

I don't happen to have any bad blocks to try this on.

Lovely.  Well then:

Someone believes that QEMU no longer benefits from kqemu.  Also, kqemu 
is incompatible with kvm.

You will need to rebuild qemu with kqemu enabled.  Attached are two 
patches:  one to be placed in rpmbuild/SOURCES, and the other to serve 
as a guide to altering the qemu.spec file (please don't use my 
initials when you set the version).  Use `rpmbuild --recompile -bp 
qemu-*.src.rpm` to unpack the files (you can interrupt the build with 
Ctl-C once you see that %prep has been started), and after altering the 
spec file, `rpmbuild -ba qemu.spec` to build with the altered spec 
file.

Sadly, you have not fixed any of the bad blocks by deleting the files.  
The bad blocks will only be replaced when they are written to.  Now 
that the files are deleted, you will need to write to all the free 
space of the drive to write to the defective blocks.  This should do 
the trick (as root, or from the Rescue CD):

# cp /dev/zero junk ; rm junk

> am now running the tar seq. above (fingers crossed)

I don't expect it to find any defective files, as you already deleted 
them.

No idea.  KVM can't use it, and doesn't need it.  I don't know what 
virt-manager would do about kqemu anyway.

The Fedora qemu SRPM was changed to eliminate kqemu from the build, 
probably because qemu-kvm can't build with kqemu and because of the 
false rumor that kqemu no longer helps.  It is not done by virt-
manager.

He gets some of them, then the test aborts.  He needs to fix at least 
those sectors in order to proceed with the test.

I don't think he uses dd.  As all the defective files have been 
deleted, the command I gave should write all the bad sectors in about 
the time to do a long test, even bad sectors that haven't been reported 
yet due to the self-test aborting (though I should have said "rm -f").

There's something under Startup Applications : Options tab.

Or maybe back up and restore, possibly with the manufacturer's low-
level format in between?

I wouldn't expect fsck to succeed if there were a bad dir file.

Yes, though I'd use "qemu*" unless you don't have the qemu metapackage 
installed.  (Personally, I just rebuild qemu when I need to use it 
after an update.)

I've added comments to closed  Bug 520284 -  KQEMU support not 
compiled after F11 QEMU-KVM merge.  You and other kqemu users may wish 
to comment there as well.)

If the above seem OK, then:

rpm -q python yum# should be python-2.6-xxx, yum-3.2.xxx
rpm -V python# should produce no output
rpm -V yum   # should produce no output or only /etc/yum.conf

It probably is not a recompile, but rather something else bad.  Anyway, 
that would be your problem with yum.  Before you rm that bad 
subprocess.pyc, what does file say about it?  You might also consider 
forcing an fsck (e.g., `touch /forcefsck ; reboot`).

OK.  Odd that it is clearly wrong, but at least it's a plausible type 
of file and an fsck does not seem indicated.

Are you sure about that?  Give an example where it happens.  (Hint.)

What surprises me from time to time is that `yum install` does not fold 
case.  I know that, and I'm still surprised.

But `yum install` does have the useful ability to install a command by 
name:

# yum install '/*/growisofs'

which is handy if you don't know what package contains the command (or 
even where the command will be installed).  The leading slash is 
required.

`yum provides` can also find files to install, but the leading "/" is 
optional, so both work:

# yum provides '*/gobject-2.0.pc'
# yum provides '/*/gobject-2.0.pc'

`yum install` gives a poor guess (here, at least) for that file.

The way recommended by QEMU developers is to use KVM, purchasing new 
hardware that supports KVM if necessary, in which case you won't need 
to use much of QEMU.  Good performance on other hardware requires the 
kernel module kqemu.  The QEMU developers have deprecated kqemu and are 
removing it from the next version (.12 IIRC), but you can currently 
still use kqemu if you build QEMU with kqemu enabled.

I have just switched from QEMU to VirtualBox (with RPMFusion enabled, 
`yum installVirtualBox-OSE`) and can recommend it, unless your VM needs 
access to your actual USB devices or needs to be controlled remotely, 
as those features are not open source.  I was able to configure 
VirtualBox to use the same disk partition (which appears as a 
partitioned disk itself) as with QEMU, and network setup was much 
easier and didn't require any equivalent to the custom scripts I wrote 
for QEMU.
