QA talk:Testcase Virtualization XenDomU Memory Ballooning
Dale 06:25, 7 May 2009 (UTC)
There isn't any guest configuration in
/etc/xen since F8 or F7.
Memory for guest can be set in libvirt
- Dump XML config if 'virsh edit' is not available (i.e. on F8 libvirt-0.4.4)
virsh shutdown f11 virsh dumpxml f11 > f11.xml
- Add currentMemory parameter which defines minimum memory given to guest at boot.
- Enact this guest config in Xen via libvirt.
virsh define f11.xml virsh start f11
- See that
free -min guest now reports 519 total.
Actually, I think I may be confused about the meaning of currentMemory as I could balloon down from 519 and back up to it, but could not go above the value of currentMemory.
