Hi there!
I have installed a new VM with Win2k8 and the serial virtio driver works fine. I
don´t know why the other VM the BSOD happen!
About the performance, I had the impression that only one core is used.....PID
8301 is a linux VM with 4 VCPU and 2 GB of RAM...
I see no problem? PID8301 uses in total 132,6% CPU equivalent consisting of
98,3% on Cpu11 and the rest scattered over other Cpu’s….

Hi there!
I will do soon the disk config, but first I will do some labs.
I´m trying to install the virtio driver to comunicate using qemu-agent but when
the driver is installed, the BSOD happens (win2k8 R2).
I tried with virtio-drivers version 100, 110 and 117, both happens BSOD.
Do you has a tip ? :)
Can’t really help you there… I’ve installed the virtio drivers on numerus
Windows systems going from Windows-XP to Windows Server 2012R2. Never had BSOD…
I do remember having some trouble with the QXL graphics driver on one specific
version of virtio, but that’s all and that should be resolved…
Thanks buddy!

Hi there!
Although the guest has 2GB memory, the windows guest was adjusted to support
this.
I guess that the LVM is the best choice! I will save all images to other disk
and re-build the partition with LVM. Do you recomend to use ext4 or zfs ?
You’ll have to convert the qcow to raw, create a LVM-volume (don’t create a file
system on the volume), and dd the raw tot he LVM volume…
- About the apparmor, I have my doubts, I will try to disable and see what will
happen!
- About the tablet input device, I removed! Some forums say that consuming idle
cpu time. I know… Never could have verivied this…
- About the guest agent, I have installed, but the first service can´t start!
The error says: A timeout was reached (30000 milliseconds) while waiting for the
QEMU Guest Agent service to connect.
You’ll have to include the qemu-ga directives in the xml, that should do the
trick:
<channel type='unix'>
<source mode='bind'/>
<target type='virtio'
name='org.qemu.guest_agent.0'/>
</channel>
[Imagem inline 1]
I´m using the virtio-win-0.1.117.iso, but I don´t know if this is updated.
Thanks for your reply and your help!

<dominique.ramaekers@cometal.be<mailto:dominique.ramaekers@cometal.be>>:
Please check virtual memory usage in the guest. 2Gb memory is very low. I think
your Windows guest is ‘swapping’ constantly. This combined with the less
performant qcow format… Reading and writing to qcow takes up host cpu…
I don’t go under 3,5Gb for Windows Guests…
Tip: Take the time to learn LVM. Changing from an image file to LVM really pays
off. I have a virtual host with RAID10 local storage. Changing to LVM gave me
more than 25% performance boost.
For the rest, it seems ok.
Less important:
I have disabled apparmor security. This was done while using an older version of
virsh and I had trouble with apparmor. I don’t know if apparmor has big
performance influence.
Wasn’t there a tablet input device? Did you delete this device? I think it’s
better to leave it. It has something to do with mouse usage in virt-viewer or
vnc…
Install the guest agent on the guest and insert the needed XML-directives. It
gives you more possibilities managing your guest like a backup with external
snapshots.

Hi folks!
When I start the Windows Server 2008 guest, the host cpu grown up the
utilization and the host load average too. Are there some tips to use Windows
Server with libvirt?
Thanks,

Could you send the XML and the result of ‘virsh version’?
