I've seen this happen on Windows VM's on plain KVM on Fedora as well.<br><br>Regards,<br><br clear="all">Maxim Burgerhout<br><a href="mailto:maxim@wzzrd.com" target="_blank">maxim@wzzrd.com</a><br>----------------<br>

Hey all,
<div><br>
</div>
<div>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 try loading it, or with installing
new guests and loading this particular driver 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´t been able to test this outside of oVirt, directly with KVM, so I don´t
know if it´s an oVirt or KVM specific issue, I´m just letting everyone know this has happened, and if ovirt-engine is supposed to use this serial interface to "talk" with the guest back and forth; that´s going to hard to do if it´s stalled:) <br>
