[libvirt] question on kvm
by hero
hello everyone:
during the days I use kvm,I have got some questions I want to know,please read the following questions.
1.When a kvm VM is running, I use 'virsh setvcpus <domain> <count>' to change the cpu numbers of the VM, and when I use 'virsh dumpxml <domain>',there is a change from '<vcpus>count</vcpus>' to '<vcpus current="currentcount">count</vcpus>', just because of this I can't start the VM after I shutdown it. could you help me about this.
2. when I use "virsh setmaxmem <domain> <value>" to change the max memory of the kvm VM, it says "error: Unable to change MaxMemorySize
error: this function is not supported by the connection driver: virDomainSetMaxMemory", I want to know if libvirt has bugs or not.
3.It works fine except I reboot the VM after I use "virsh setmem <domain> <value>" to change the kvm VM boot memory, for example, I change the memory 3000000k, but it can not save the value the next time to reboot.
Best wishes and Merry Christmas!

[libvirt] [PATCH] tests: run schema checks in sorted order
by Eric Blake
Having a test that depends on file system timestamps and/or inode
allocation order is non-deterministic in its output.
* tests/schematestutils.sh: Run test in deterministic order.

Pushing under the trivial rule. Evidence of the non-determinism
can be found at the location of the three failures reported here:

[libvirt] [PATCH v2] virsh: Add two new commands to change media
by Osier Yang
eject-media to eject the media from, and insert-media to insert
media into CDROM or floppy drive.
---
Basically this patch is just rebaing of
https://www.redhat.com/archives/libvir-list/2011-June/msg01516.html,
with a bit improvement, as I explained in the mail thread, we
don't have to wait for the new QEMU monitor commands, what we
need is just separate the tray and media management in virsh,
if one day QEMU gets the patch for those new commands pushed,
we can switch to honor them easily (regardless of whether we do
it inside updateDeviceFlags API or in new APIs).

Latest patch a1a83c587443 introduces new qemu capability flag
QEMU_CAPS_FSDEV_READONLY. However, it was missing in qemuhelptest
making test for qemu-1.0 fail.

[libvirt] [PATCH] Add new attribute writeout to <filesystem> element
by Deepak C Shetty
This introduces new attribute writeout with only supported
value as immediate. This will be an optional
attribute with no defaults. This helps specify whether
to skip the host page cache.
When writeout is specified, meaning when writeout=immediate
a writeback is explicitly initiated for the dirty pages in
the host page cache as part of the guest file write operation.
Usage:
<filesystem type='mount' accessmode='passthrough' writeout='immediate'>
<source dir='/export/to/guest'/>
<target dir='mount_tag'/>
</filesystem>
Currently this only works with type='mount' for the QEMU/KVM driver.
Signed-off-by: Deepak C Shetty <deepakcs(a)linux.vnet.ibm.com>
