Hey all,
I have noticed that using the virtio serial driver in Windows 7 and 2008R2 =
guests stalls the guests with 100% load on guest CPU. This happens both on =
guests that have been active for a while without the driver, and then you t=
ry loading it, or with installing new guests and loading this particular dr=
iver in the windows installer. I have downloaded the virtio-win-0.1.30.iso =
from linux-kvm ftp. Has anyone else noticed this in oVirt-3.1? I haven=B4t =
been able to test this outside of oVirt, directly with KVM, so I don=B4t kn=
ow if it=B4s an oVirt or KVM specific issue, I=B4m just letting everyone kn=
ow this has happened, and if ovirt-engine is supposed to use this serial in=
terface to "talk" with the guest back and forth; that=B4s going to hard to =
do if it=B4s stalled:)
Med V=E4nliga H=E4lsningar
