[kvm-devel] [PATCH] Getting 32-bit Vista on KVM
Now I realized that I needed to use 32-bit Linux to build the bios.bin
(i.e. BIOS-bochs-latest) in bochs. As long as I used x86-64 Linux to
build bios.bin, the resulting binary had a problem, as I reported
previously.
With this very simple patch, I was able to install and run 32-bit Vista
on KVM (almost the latest tree) on the 64-bit host. Thanks Qing for
debuging this. I believe this should work for Qemu as well.

You could do it the way that ext2 handles compatible and incompatible
features in the on-disk layout:
Assign a number of bits in the read-only part of the mapping to flags
that the user application can test. A bit in the compatible range mean
that a feature is available to the user application if it wants to
use it. A bit in the incompatible range means that the user space needs
to understand how to use a feature in order to run correctly.

Not sure about that point. If you need to do atomic operations on the
first 32 bits, you shouldn't need to invent your own abstractions for
those, and it's highly unlikely that the implementation of atomic_t changes.

After a while using X (while the kvm qemu vm is running in the background), the video corrupts slightly (black vertical bars) and the (USB) mouse gets stuck to the left border of the screen. It can be moved away very slowly, but if you do it too fast it jumps back to the left border. Restarting X solves the problem for a short time, but once it happens, it happens again and again. Shutting down qemu and rmmod-ing the kvm modules does not help once the problem occurs. I have to reboot to make it go away. I saw some other people mentioning similar symptoms mainly with fedora systems and unrelated to kvm, but I run Ubuntu and have isolated the problem to be connected with kvm-21. kvm-19 works just fine. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1710701&group_id=180599 - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

How big is your initrd image ? There was a QEMU bug which causes the
end of the initrd to be overwritten by the kernel if the initd was
larger than 1 MB IIRC. Upstream QEMU CVS has the patch, but the current
KVM SVN repo does not seem to have it. I'm attaching the patch we applied
to KVM-19's copy of QEMU in Fedora to fix, although it doesn't apply cleanly
to current KVM dev.

Dan.

You don't have to purge anything. If you have an existing Xen guest,
you can work with it as is; no need to install grub if you dont want
to. For new installs, of course it is easier to fire up the native
installer which does everything for you.
Things like updating the guest kernel and initrd are usually much easier
if the kernel is contained within the guest disk image. Similarly,
copying an image or backing it up is simpler if you don't have to worry
about the kernel.

Guest performance will be lower, but just for the test. The -no-kvm
option is very useful in determining whether the problem is in the
kernel or userspace.

But.. but Xen is the one true master of virtualization technology,
anyone who comes after must blindly follow or perish in the fires of
their own creation!!
But, anyway... So I should be installing boot loaders to the guest
OS's? hmmm I'll have to figure out how to do that since I don't think
I installed grub. Also, are their any other Xenism's that I have to
purge before continuing?
Also, I'm kinda afraid to try this with --no-kvm from what I
understand that will drastically reduce the performance of the guest
and host OS, is that true?

The ioctl interface and the syscall interface have to call the same internal API, so at least some refactoring is needed. -- error compiling committee.c: too many arguments to function - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

The ioctl interface isn't going away. Maybe I misunderstood. When you said this: > I think we can start the syscall based API (with compatibility ioctls > for x86), now that we have all four archs looking at it. I thought you meant that all architectures would use the syscall interface, and x86 would only continue to support the ioctls as a legacy interface. In that case, I think kvm_main.c would basically need a rename to kvm_ioctl.c, and it would be built only for x86 so wouldn't need any portability. -- Hollis Blanchard IBM Linux Technology Center - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

I suspect that on a Core 2 you will see faster speeds, and more improvements are promised with newer processors. Note that recent kvm versions have improved vmexit latency independently of the processor, and this is continuing too. -- error compiling committee.c: too many arguments to function - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [kvm-devel] KVM management and API
I'll try to answer the open questions. Btw, libvirt is a great project and a very good option for managing kvm. In the future use plain text for the list messages. From: jd [mailto:[EMAIL PROTECTED] Sent: Saturday, April 28, 2007 8:12 AM To: Daniel P. Berrange Subject: Re: [kvm-devel] KVM management and API Thanks Daniel. But I was looking for bit of under the hood answers. For cpu /proc seems to be used.. which seems fine, but will not work for QEMU on Windows. KVM is not supported in Windows host anyway. Some core qemu quesions still remains -- what are the plans to dynamically be able to change cpu , mem, disks and n/w for a running vm ? When we'll support SMP you could add vcpus dynamically. The same for hotplug memory slots. Regarding disks, you can post it in qemu's list. -- proper shutdown/restart of VM ? Currently powerdown/restart are supported. Hoping some kvm/qemu experts would thrown in some light on the directions and plans. Thanks in advance. /Jd "Daniel P.
