Hi guys,
I'm facing some problems in keeping my Windows 2000 virtual machines up
and running. Every machine resides on a drbd storage, with this disk setup:
<disk type='block' device='disk'>
<driver name='qemu' type='raw'/>
<source dev='/dev/drbd0'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' unit='0'/>
</disk>
I installed the virtual machine without any problem, but sometimes it
freeze. I mean, the only way I have to make it work again is killing the
kvm process by hand:
/usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp
1,sockets=1,cores=1,threads=1 -name vm-win2k -uuid
806d0e99-b164-c77d-96eb-55d24d3ba06b -nodefaults -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/vm-win2k.monitor,server,nowait
-mon chardev=monitor,mode=readline -rtc base=localtime -boot c -drive
file=/dev/drbd0,if=none,id=drive-ide0-0-0,boot=on,format=raw -device
ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive
file=/root/vmwarevga32-kvm.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw
-device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0
-device rtl8139,vlan=0,id=net0,mac=52:54:00:a3:5b:1b,bus=pci.0,addr=0x3
-net tap,fd=44,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device
isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -vnc
0.0.0.0:0 -k it -vga vmware -device
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4
and restart the machine with virsh start.
Today i saw this page:
http://www.linux-kvm.org/page/Guest_Support_Status
in which is explained how is better to run win2k on qcow2 images.
My question are: is this the reason why my machines freezes? Is it
mandatory using qcow2 images to have stable machines? How using directly
drbd make things worst? Is there a way for using qcow2 images WITH drbd?
I mean, without formatting drbd with ext3 and put the image on it...
Thanks a lot,
