similar to: VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON meaning

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 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, 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, 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, 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, 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 , 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, I need to add , via script , a channel device in .xml guest config file. Is virsh edit useable from a "standard" script or is there any more suitable way to use ? Thanks. J.P.

Hi, As using a blocking socket for a virtio device channel leads to be blocked if nobody has opened the corresponding /dev/virtio-ports within the Guest , I tried to use a non-blocking socket and to check whether the socket is writeable via FD_ISSET(). I'm wondering why a virtio device channel is always seen as writeable by the Host even if nobody has opened the corresponding

Hi, Is there "faster" way than calling virDomainGetXMLDesc() and parsing the result to retrieve the state field ( connected or disconnected) of a channel device ? Thanks. J.P.

Hi, >From a Windows Guest , I try to read data sent by the Host , via a virtio port . ( I.e. channel device type UNIX on host side) If no data sent by Host , the blocking ReadFile() invoked within the Guest exits immediately with following error code : ERROR_NO_SYSTEM_RESOURCES 1450 (0x5AA) Insufficient system resources exist to complete the requested service. Is it the waited behavior

Hi, Is there an equivalent of "virsh attach-device -live -persistent " within libvirt API : virDomainAttachDevice() or virDomainAttachDeviceFlags() or ??? Thanks for help. Regards, J.P.

Hi, Did anybody ever try to script « virsh attach-device ...... < response.txt" in order to give virsh user and password needed when host is part of a ovirt cluster ? Cos , although I put in my response.txt two lines one for user the other for password , then it always asks question concerning password. ( username is correctly got from the .txt file.)
