Hi All, We are trying to do "virsh managedsave" on a VM but it is failing with the following error. libvirtError: operation failed: domain save job: unexpectedly failed^M libvirt and qemu versions are as follows: libvirt-1.1.1-29.el7.x86_64 qemu-kvm-1.5.3-60.el7_0.11.x86_64 VM is provided with a small pxe image such that it pxe boots from a remote server. VM doesn't have any disk allocated with it and uses 4GB RAM,16 VCPUs. It mounts the root storage and all required folders from a remote server's NFS storage. Following is the file system once the VM is booted successfully. VM1:~ # df -h Filesystem Size Used Avail Use% Mounted on rootfs 2.0G 1.5G 601M 71% / root 2.0G 1.5G 601M 71% / tmpfs 7.1G 3.4M 7.1G 1% /dev/shm shm 7.1G 3.4M 7.1G 1% /dev/shm
One weird thing is that if the guest has 4GB of RAM, how come it has tmpfs mounted with the size of 7.1G? And with shared memory the size of 3.4GB.
10.0.0.3:/.storage 90G 20G 66G 23% /storage We have also tried to enable debug mode for libvirt process but no error message is getting logged except the error message above. Could someone help me debug this issue?
How did you enable the logging? Have a look at our wiki [1] in case of troubles with that. And "unexpectedly failed" means libvirt won't know why it happened, but probably there could be something in the domain log (what QEMU spat out), see /var/log/libvirt/qemu/<domainnamehere>.log [1] http://wiki.libvirt.org/page/DebugLogs
