How to retrieve legacy cgroups location ?
Hi,
As told in "Control Groups Resource Management" libvirt page :
Legacy cgroups layout
Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was

Guest cpuacct counters and others location
Hi,
My piece of code ( C langage) uses cgroups to retrieve counters related to cpu and memory usage related to KVM guests hosted by the host where this code runs.
I noticed that depending on the O.S. running on the host , these counters are not found at the same location :
CentOS 7 :
ls /sys/fs/cgroup/cpuacct/machine.slice/machine-qemu\\x2drhel6.0.scope/vcpu0

Re: operation forbidden Read Only Access
Hi,
I found an answer :
Use virConnectOpenAuth() instead of virConnectOpenReadOnly().
As my piece of code is running silently (without user connected) , by using virConnectOpenAuth() ,
is it possible to avoid to prompt user to get user /password ?
Thx.

Re: libvirt-users Digest, Vol 73, Issue 12 ] Failure when attaching a device
Hi,
I think that issue is due to the fact that my Guest is a transient domain.
When shutting down it or migrating to another host , then virsh list --all doesn't show this Guest anymore.
How may I make this Guest a persistent one ?
( i.e. this Guest has been created via RHEV-M GUI)
Thx for hlep.

When adding a channel device, we need a shutdown
Hi,
It looks like , when adding a channel device, that the Guest must be powered off / on to be able to detect
the new device . ( simple reboot isn't not enough)
Is there any way to avoid this power_cycle ?
Thx.
