There is an apparmor rule in /etc/apparmor.d/abstractions/libvirt-qemu denying access to /tmp and /var/tmp. More details here, https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1403648 With Save, libvirt writes to the save file using iohelper which is allowed as qemu is not directly accessing the /var/tmp but restore is from the file FD directly. So, restore with --bypass-cache should work here which uses the iohelper. I noticed on 16.04, 17.04 & 17.10 the -bypass-cache also fails with error: internal error: Child process (LIBVIRT_LOG_OUTPUTS=1:stderr /usr/lib/libvirt/libvirt_iohelper /var/tmp/save.file 0 0) unexpected exit status 1: /usr/lib/libvirt/libvirt_iohelper: Unable to read /var/tmp/save.file: Invalid argument I see the above is fixed upstream with the commits 776b9ac594b6a1e4afc924826c6e9cb5474e8e27 f830e371ef298e7fa949165d10dcf0cf3518abd5 3b8a0f6ac23e4d4620218870030a08f75419b5d7 05021e727d80527c4b53debed98b87b565780a16 633b699bfda06d9fcdb7f9466e2d2c9b4bc3e63c Thanks, Shivaprasad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1719579 Title: [Ubuntu 16.04.2] [libvirt] virsh restore fails from state file saved in /var/tmp folder using virsh save To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1719579/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
