Hi, By trying to add this device : <channel type='unix'> <source mode='bind' path='//var/lib/libvirt/qemu/VM_RHEL7-1_omnivision_1.agent'/> <target type='virtio' name='omnivision_1.agent'/> </channel> Within config file by issuing virsh edit , I got following error when to saving the config file : Unable to validate

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 cgroup.clone_children

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. Regards, J.P. -----Message d'origine----- De : libvirt-users-bounces@redhat.com

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

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 .

Hi, I' trying to read datas sent by my KVM host within the Guest. Host send these datas trough a channel UNIX type , by using AF_UNIX socket stuff. If i try to retrive the datas by using such type of thing in the Guest : #define NAME "/dev/virtio-ports/agent" sock = socket(AF_UNIX, SOCK_STREAM, 0); 12 if (sock < 0) { 13 perror("opening stream socket");

Hi, I'm facing following issue ( or misunderstanding from my side) I try to attach a device to a running guest ; I want to do it persistently and without having to restart the GUEST .

I added my host in a ovirt cluster , and then , when running the script creating the channel device ( by using "virsh attach-device --persistent -live ....."
