[Users] Using vioserial in Win7/2008R2 stalls the guest

[Karli Sjöberg]

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 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:)
