We suspect it may be a permissions bug in the way xenstore is set up by XAPI.
# list_domains id | uuid | state 5 | 0dae370c-753d-5ef0-e3e0-e3a5e93d6203 | B # xenstore-ls -fp | grep /vm/0dae370c-753d-5ef0-e3e0-e3a5e93d6203/uuid /vm/0dae370c-753d-5ef0-e3e0-e3a5e93d6203/uuid = "0dae370c-753d-5ef0-e3e0-e3a5e93d6203" (n0,r1) This suggests that even though the domain ID post-reboot has been updated, the xenstore permissions have not been updated (the domain was previously domain 1 - hence the r1 permission) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1081182 Title: issues accessing /sys/hypervisor/uuid when rebooting VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xen-api/+bug/1081182/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
