Re: [CentOS-virt] xen and spice problem

2015-10-04 Thread Mark Pryor
http://107.185.144.55/xen/cent7/dom0/RPMS/stable-4.6/mock/
above is a build of upstream xen with this `configure` including spice 
support:./configure --enable-systemd --prefix=/usr --enable-xsmpolicy 
--enable-ocamltools \
  --libdir=%{_libdir} --enable-efi \
  --with-extra-qemuu-configure-args="--enable-spice --enable-usb-redir"
there is no associated libvirt buildIncluded are patches up to the HEAD of 
staging-4.6, so its basically rc5.--

there is an qemu 2.0 ver in EPEL (qemu-2.0.0-1.el7.5 RPM for x86_64) 
there is the spice support build in...

Re: [CentOS-virt] adding xen support to grub2 got segfault running grub2-mkimage

2015-09-16 Thread Mark Pryor

I have properly packaged a split off of xen support in grub2 for Centos 7.
No more segfaults.
I have not seen anyone attempt to package this starting with the official C7 
SRPM from the vaults.

 There is some interest lately in making a self-contained grub2 boot image - 
call it pvgrub2, used for booting paravirtual domU in xen where a grub2 config 
is installed.
First attempt--
I first tried using the grub2*.src.rpm from the C7 vault.
I configured as shown 
belowhttps://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/
for headers, I used xen-devel, xen-libs, xen-licenses from a recent build I 
didhttp://107.185.144.55/xen/cent7/dom0/RPMS/stable-4.5/mock/
this gave a segfault from grub2-mkimage with a cmdline 
like/usr/bin/grub2-mkimage  -O x86_64-xen   -C auto  -d 
/usr/lib/grub/x86_64-xen -c ./grub-bootstrap.cfg -m ./memdisk.tar -o 
./grub2-x86_64-xen.bin -v  ext2 fat file font fshelp gzio halt hashsum help 
legacycfg linux loadenv loopback part_dvh part_gpt part_msdos part_plan 
part_sun xfs xnu_uuid xnu_uuid_test xzio
the image would finish if I cut down the module list to about 8 or less 
modules. This is not enough for a useful image .

Second AttemptIn the same build env, I started with the git 
clone (see link). Now when running grub-mkimage I included all the modules 
in/usr/lib/grub/x86_64-xen/ and the image formed without error and works as 
expected as a xen bootloader.
The only difference in the two builds is the size of grubX-mkimage: one is 
stripped and the other not. Using the official grub2 C7 packages failed and a 
rogue build from git worked.

Re: [CentOS-virt] C7 with Xen support

Hi all,

Anybody could me tell when CentoOS7 will have Xen support?

Thank a lot

Volnei,
I don't speak for the C7 project so this reply is unofficial. RH has disabled 
all dom0 kernel support found in mainline kernel. DomU support is mostly intact.

I have a xen 4.4.0 dom0 on C7 since July 16, but using the kernel-ml (3.15) 
from elrepo.org

Got my xen package set by rebuilding xen-4.4.0-8.fc22.src.rpm from here
ftp://ftp.muug.mb.ca/mirror/fedora/linux/development/rawhide/source/SRPMS/x/

The Fedora developers are adapting xen to systemd rapidly, so the above SRPM 
can change weekly.

If you or anyone else wants more detail, find PryMar56 on #xen on freenode IRC.

cheers,
Mark

 Hi all,
 
   Somebody knows how can I extract/know an ip address
 used by a kvm 
 guest using a script?? For example I have the following
 guests:
 
 [root@kvmsrv01 bin]# virsh list --all
   Id Name           
      State
 --
    1 linclunode01     
    running
    2 linmgmt       
       running
    5 win7desktop       
   running
 
 
   I know that linclunode01 has 172.25.50.1 as ip
 address, linmgmt has 
 172.25.50.2 and so on. But suppose that i don't know which
 ip address is 
 used by win7desktop guest. The real fqdn for win7desktop is
 
 win7.local.net. How can I know its real ip using a script
 (bash, python, 
 etc)?? I don't use a dhcp or dns server on this network.

If you have an http server on the local network:

Inside the VM guest:

 /etc/rc.local 
wget --spider http://192.168.1.1/favicon.ico?sl6bs?ga-p45
 snip -

where the web server is at 192.168.1.1, Virt host is ga-p45, and the VM guest 
is sl6bs.

In the server logs I see:
$ sudo tail -n 175 /var/log/apache2/local_log | grep fav
192.168.1.224 - - [23/Apr/2011:10:10:02 -0700] HEAD 
/favicon.ico?lucidpv?ga-p45 HTTP/1.0 200 296
192.168.1.155 - - [23/Apr/2011:10:10:10 -0700] HEAD /favicon.ico?centbs?ga-p45
