[libvirt] error: Failed to start pool (already mounted)
by Ragnar Skúlason
Hi everyone,
I'm not sure if this belongs here, I sent a question to the users list
yesterday without getting a response, so I'm trying here.
I have storage-pool that for some reason became inactive (possibly due to
an error with pool-refresh in an old version of a Java API binding).
I want to restart the pool but am unable to, due to the volume being
mounted:
# virsh pool-start [uuid]
error: Failed to start pool [uuid]
error: Requested operation is not valid: Target '/mnt/[uuid]' is already
mounted
We have tested this with versions 0.9.12 and 0.9.13.
This did work in versions 0.8.x
Is it possible to bypass this mount check and start the storage pool
(forcefully)?
Many thanks,
Ragnar Skúlason

[libvirt] Problen in cloning of thin LVM
by Pankaj Rawat
Hi all,
I have create a Thin lvm and installed a guest os on it,
Now when i cloned that lvm using virt-clone
# virt-clone --prompt --force --original lvm_thin1 --name lvm_thin2 --file /dev/volgrp/lvm_thin2
The cloned Disk lvm_thin2 size is fully expanded , But I want a thin Lvm cloned image
Well according to my best of knowledge , It could be because the when lvm is getting cloned, The zero are read from the original image
#lvs
LV
VG
Attr
LSize
Pool Origin
Data%
lvm_thin1
Volgrp
Vwi-aotz
8.00g
pool
12.18
lvm_thin2
volgrp
Vwi-a-tz
8.00g
pool
100.00
pool
volgrp
twi-a-tz
100.00g
8.97
As you can see above the original LVM utilize only 12.18% disk space from the pool, but the cloned lvm_thin2 is fully expanded.
Is there is any way how can I clone a THIN LVM without fully expanding it ? Or Is there any way to shrink the cloned LVM to that size without loss of data.
Regards
Pankaj Rawat

[libvirt] [PATCH 0/4] Initial OpenBSD support
by Jasper Lievisse Adriaanse
Hi,
Here are some patches to get libvirt building on OpenBSD. I tested basic functionality
with virt-manager though there appear to be some rough edges to fix/polish (could also be
in virt-manager). At least basic libvirt usage should work on OpenBSD now.
Jasper Lievisse Adriaanse (4):
Define DYNLIB_NAME on OpenBSD.
Fixup some headers in virnetdevbridge.c, needed for OpenBSD.
Check for sys/ucred.h and adjust virnetsocket.c for OpenBSD
compilation.
There's no librt on OpenBSD.

[libvirt] [PATCH 0/4] Support to set disk wwn
by Osier Yang
This introduces new element <wwn> for disk, to allow to set wwn
(just like setting serial number) for the virtual disk (Only QEMU
devices like ide-drive, ide-hd, ide-cd, scsi-disk, scsi-hd, and
scsi-cd support it).
Osier Yang (4):
schema: Add schema for disk <wwn>
conf: Parse and format disk <wwn>
qemu: Add caps to indentify if setting wwn is supported by qemu
qemu: Use disk wwn in qemu command line

[libvirt] [RFC PATCH v1 0/4] Add cpu hotplug support to libvirt.
by Tang Chen
It seems that libvirt is not cpu hotplug aware.
Please refer to the following problem.
1. At first, we have 2 cpus.
# cat /cgroup/cpuset/cpuset.cpus
0-1
# cat /cgroup/cpuset/libvirt/qemu/cpuset.cpus
0-1
2. And we have a vm1 with following configuration.
<cputune>
<vcpupin vcpu='0' cpuset='1'/>
<hypervisorpin cpuset='1'/>
</cputune>
3. Offline cpu1.
# echo 0 > /sys/devices/system/cpu/cpu1/online
# cat /sys/devices/system/cpu/cpu1/online
0
# cat /cgroup/cpuset/cpuset.cpus
0
# cat /cgroup/cpuset/libvirt/qemu/cpuset.cpus
0
# cat /cgroup/cpuset/libvirt/lxc/cpuset.cpus
0
4. Online cpu1.
# echo 1 > /sys/devices/system/cpu/cpu1/online
# cat /sys/devices/system/cpu/cpu1/online
1
# cat /cgroup/cpuset/cpuset.cpus
0-1
# cat /cgroup/cpuset/libvirt/cpuset.cpus
0
# cat /cgroup/cpuset/libvirt/qemu/cpuset.cpus
0
# cat /cgroup/cpuset/libvirt/lxc/cpuset.cpus
0
Here，cgroup updated cpuset.cpus，but not for libvirt directory，and also qemu and lxc directory.
vm1 cannot be started again.
# virsh start vm1
error: Failed to start domain vm1
error: Unable to set cpuset.cpus: Permission denied
And libvird gave the following errors.
2012-07-17 07:30:22.478+0000: 3118: error : qemuSetupCgroupVcpuPin:498 : Unable to set cpuset.cpus: Permission denied
These patches resolves this problem by listening on the netlink for cpu hotplug event.
When the netlink service gets the cpu hotplug event, it will attract the cpuid in the message,
and add it into cpuset.cpus in:
/cgroup/cpuset/libvirt
/cgroup/cpuset/libvirt/qemu
/cgroup/cpuset/libvirt/lxc
Tang Chen (4):
Add cpu hotplug handler for netlink service.
Register cpu hotplug netlink handler for libvirtd.
Register cpu hotplug netlink handler for qemu driver.
Register cpu hotplug netlink handler for lxc driver.
