[CentOS-virt] CentOS 6.2 / kvm / Windows XP sp3 guest crashes repeatedly after a few minutes

[Philip Bondi]

Hello to all:

Recently upgraded from CentOS 6.0 to 6.2 to get USB passthrough support by 
performing "yum update".  USB passthrough works great, but now my Windows XP 
sp3 guest crashes repeatedly after a few minutes.

CentOS 6.0 was stable.  Windows XP sp3 did not crash.

Formerly, I was running virtio-win-0.1-15.iso, but now upgraded to 
virtio-win-0.1-22.iso and Windows XP sp3 remains unstable.

[CentOS-virt] Installing Ubuntu 10.04 Lucid guest on Centos 5 using virt-manager

[Dennis Jacobfeuerborn]

Hi,
i'm trying to install an Ubuntu Lucid PV guest on a Centos host but I can't
seem to find a working installation URL. I tried
"http://ftp.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/"; and
various subdirectories but I always get the error "Could not find an
installable distributio at ...". In the OS Variant box I chose Ubuntu 9.04
as that is the closest to what I'm trying to install.

Any idea how this works?

Regards,
  Dennis
