similar to: Re: channel device "state" value missing within OpenStack Kilo version

Hi, I've installed a OpenStack KILO all-in-one . For private need , I've to add a channel device to all my GUESTS on my compute node. It works fine (e.g. via a virsh command). Problem is that , in the xml describing the Guest , this 'state' value : <target type='virtio' name='agent' state='disconnected'/> showing if the channel is connected

Hi, I just tested by using "unix virtio" channel instead of pty. It looks easier to handle. Thx for help.

Hi, I try to exchange datas between host and Guest by adding these lines in a guest .xml conf file : <channel type='pty'> <target type='virtio' name='arbitrary.virtio.serial.port.name'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> Then

Hi, In which libvirt version are these virDomainMemoryStats() counters handled ? VIR_DOMAIN_MEMORY_STAT_SWAP_OUT VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT VIR_DOMAIN_MEMORY_STAT_UNUSED VIR_DOMAIN_MEMORY_STAT_AVAILABLE Thanks. Regards, J.P.

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.

Hi, I'm trying to find out what is the minimum release I need to use to have this field 'state' available ? <channel type='unix'> <source mode='bind' path='//var/lib/libvirt/qemu/dummy_agent'/> <target type='virtio' name=dummy' state='connected'/> <alias name='channel0'/> <address

Hi, I'm wondering how to explain following metrics I got from libvirt, regarding memory stats for the two GUESTS running on my host. 1) virDomainGetXMLDesc() shows these values : memmax (1024000.000000) memcurrent(1024000.000000) memmax (2048000.000000) .memcurrent(2048000.000000) 2) As values returned by virDomainMemoryStats(), I got these values :

Hi, By using libvirt-1.2.8-16.el7_1.3.x86_64 , it looks like there are 3 virDomainMemoryStats tags available : VIR_DOMAIN_MEMORY_STAT_SWAP_IN VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON VIR_DOMAIN_MEMORY_STAT_RSS Is there a plan to add the other ones ? Meanwhile , do you know which metrics ovirt uses to display memory column value in the manager GUI ? Thx. J.P. Ribeauville P:

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, 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. Regards, J.P. Ribeauville P:

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, 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 , Despite the fact that my Guest has an IP address , by running this piece of code on a KVM host : ifaces_count = F_virDomainInterfaceAddresses(domain, &ifaces,VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_LEASE, NULL); ifaces_count = F_virDomainInterfaceAddresses(domain, &ifaces,VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_AGENT, NULL); I'm not able to get a ifaces_count different from

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, By adding following lines in a Guest .xml conf file , I'm able to send / receive datas between host and this guest. <channel type='pty'> <target type='virtio' name='arbitrary.virtio.serial.port.name'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> My question is

Hi, I add the device in the .xml conf file using this way : <channel type='unix'> <source mode='bind' path='//var/lib/libvirt/qemu/omnivision_1.agent'/> <target type='virtio' name='omnivision_1.agent' state='disconnected'/> <alias name='channel1'/> <address type='virtio-serial'
