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.

vdsm hook issues
Hi,
1) is it enough to add a hook.py in /usr/libexec/vdsm/hooks/before_vm_start directory , and then shut down and reboot a guest to
see this hook.py invoked ?
2) when running manually my hook.py, I got following error :
ImportError: No module named hooking
Do I have to install anything to solve this issue ?
Thanks for help.

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

Network interface name of guest via python API
Hi,
I'm trying to get some basic data from running guests on a libvirt HV
but one thing I'm missing is the name of the network interfaces of the
guests. I can get the MAC address from the XML but there seems to be no
function to actually get the name of the interface.
The only function that comes close is this one:

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.

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.
