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.

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 mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
