[ovirt-users] oVirt Windows Guest Tools & Live Migration issues.

[Anantha Raghava]

Hello Michal,

Guest tools are working and getting all details about guest vm as needed.

But one thing I didn't understand. What is the relationship between 
virtioserial driver and oVirt Guest Service? Without virtio serial 
driver, guest services does not start.

Also, how do we install memory baloon driver?

Tomorrow morning, I will post about Live Migration events after I 
attempt it.

Thanks & Regards,


Anantha Raghava
