similar to: virsh "cpu-stats" not working !!!

Hi Eric, Thanks for your valuable time and comments. >> Are you sure cpuacct was mounted prior to libvirtd starting? Yes, we are mounting cpuacct before starting the libvirtd daemon. >> Libvirt won't mount cgroups; Yes, Agree. >>it only uses what was mounted at the time it was started. But we are mounting it well before it is started. We are facing the issue only while

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name

We're going to need a bit more information about the hardware in the physical server, like what 'RAID 0' means - hardware RAID? What precise RAID controller

Dear All, Please find few minutes from your time and guide us with some pointers if possible. We are facing a libvirtd crash when we are trying to connect to qemu by default TLS transport. # virsh -c qemu+tls://localhost/system version error: authentication failed: TLS handshake failed A TLS packet with unexpected length was received. error: failed to connect to the hypervisor I used my own CA

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 Daniel, Thanks a lot for your reply. We have mounted all the cgoup controllers at "/dev/cgroup_<controller>" as mentioned below. ls /dev/ | grep cgroup cgroup_cpu cgroup_cpuacct cgroup_cpuset cgroup_mem On further debugging we dound that the "VCPU" directories are not being created for our domains and hence the comamnd "cpu-stats

Hi, With a non-root user account, I am launching virtual machines and would like to get CPU stats for each Core (using python API or not) but face the following problem: - When I issue the command "virsh --readonly cpu-stats MY_DOMAIN" I got the following error: error: Failed to retrieve CPU statistics for domain 'MY_DOMAIN' error: Requested operation is not valid: cgroup

Minor Correction, Yes, we are using Hardware RAID-0, which uses HP Smart Array P220i Controller.

I have a RHEL6 that hosts many kvm virtual machines. It has been working fine for a couple years. I apply errata updates about once a week. In the last couple weeks, I've ran into a bug where the virtual machines start failing to start with a cgroup error message. If I reboot the host (very disruptive) then things start working normaly for a few days. Can I configure qemu/libvirt not to use

Hi, We are implementing feature called CPU separation in the platform. So, guest VMs will have dedicated cores allocated using cgroups (cgroups hierachy related VMs managed by libvirt). virsh cpu-stats command is not working in our platform : virsh # cpu-stats test_vm error: Failed to virDomainGetCPUStats() error: Requested operation is not valid: cgroup CPUACCT controller is not mounted It

Hi Sir, ?Thanks for your immediate reply. ?I have checked all the logs and outputs for the same application as ?you have suggested.

Hello, Does it exist some documentation concerning following topic ? What's difference between following perf counters : /cgroup/cpuacct/libvirt/qemu/test/cpuacct.usage and /cgroup/cpuacct/libvirt/qemu/test/emulator/cpuacct.usage Thx . Regards, J.P.

Hello, R subscribers. I would like to define a function like this one: Fun <- function(x) sin(x)/x with value 1 at x=0. How can I do that? Is there a way to plot it "symbolically", without using x as a vector? e.g. x <- seq(from=-10, to=10, length=100) plot(x, Fun(x)) Thank you in advance.

Dear list, I am bulding a VM using libvirt and lxc for linux container. I have an issue with my cgroups settings: gabx@hortensia ➤➤ ~ # virsh start dahlia error: Failed to start domain dahlia error: internal error: No valid cgroup for machine dahlia My environement: Host : Arch Linux - systemd 208-11, libvirt 1.2.1-4 guest : Arch Linux , machine name : dahlia , /etc/libvirt/lxc/dahlia.xml ,

Hello, R users. I have the following code: a=1:10 b=-3:15 n=5 x <- rep(0,n) for (i in 1:n) x[i] <- sum( outer(a,b, function(s,t) abs(a-b-i)==0) ) Can someone tell me if I could avoid the for command? Thank you in advance.
