Can't boot virtio-guest with KVM since kvm-86

Hello,

since kvm-86 I can't boot a Debian Lenny guest machine. When I boot the machine I get the following error:

I tried to reinstall the machine, but during the install process the installer isn't able to create a swap partition. Later, I got the error message "stale NFS file handle" at the console (I don't do anything with nfs here). Same errors with kvm-87 and 88.

I tried to install other distros, but any of them failed to install on the virtio disk one way or another.

Everything works with kvm-84. With kvm-85 libvirt (which I am using) wasn't able to boot from a virtio disk. Note that libvirt has nothing to do with the error/bug described above. This happens since kvm-86 with plain kvm started from the command line, too.

I am switching back to kvm-84 for now.

To reproduce:
Get a Debian Lenny qemu/KVM image and virtio disk and try to boot it. Or try to install Debian Lenny on a virtio disk. There were other errors with other Distros, so I suspect that there is somesthing wrong with kvm since 86.

Welcome to the forum haary!

Do you have Archlinux host, 32 bit or 64 bit ? Does it works under other host ?

mthode · 2009-08-17 23:50:42

I am also having the same problem, the host is Archlinux with kvm-88 on 64bit, I am going to try aur and see how it goes when I get home.
There is no updated aur package so downgrade it is.

KVM 84 didn't work YES!!!
