A quick update. I have done a fresh install of the CloudStack host server running Ubuntu 18.04 with the latest updates. I've installed ceph 12.x and connected it to Cloudstack which uses kvm/libvirt/ceph/rbd. The rest of the ceph services (mon,mgr,osd,etc) are all running 15.2.3. Works like a charm. As soon as I've updated the host server to version 15.2.3, Libvirt stopped working. It just hangs without doing much it seems. Common commands like 'virsh pool-list' or 'virsh list' are just hanging. I've strace the process and it just doesn't show any activity. 2020-07-06 18:18:36.930+0000: 3273: info : virEventPollUpdateTimeout:265 : EVENT_POLL_UPDATE_TIMEOUT: timer=993 frequen cy=5000 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollUpdateTimeout:282 : Set timer freq=5000 expires=1594059521930 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollInterruptLocked:722 : Skip interrupt, 1 140123172218240 2020-07-06 18:18:36.930+0000: 3273: info : virEventPollUpdateHandle:152 : EVENT_POLL_UPDATE_HANDLE: watch=1004 events=1 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollInterruptLocked:722 : Skip interrupt, 1 140123172218240 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollCleanupTimeouts:525 : Cleanup 8 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollCleanupHandles:574 : Cleanup 22 2020-07-06 18:18:36.930+0000: 3273: debug : virEventRunDefaultImpl:324 : running default event implementation 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollCleanupTimeouts:525 : Cleanup 8 2020-07-06 18:18:36.930+0000: 3273: debug : virEventPollCleanupHandles:574 : Cleanup 22 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=0 w=1, f=5 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=1 w=2, f=7 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=2 w=3, f=10 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=3 w=4, f=11 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=4 w=5, f=12 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=5 w=6, f=13 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=6 w=7, f=14 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=7 w=8, f=15 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=8 w=9, f=16 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=9 w=10, f=17 e=1 d=0 2020-07-06 18:18:36.931+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=10 w=11, f=18 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=11 w=12, f=19 e=0 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=12 w=13, f=19 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=13 w=14, f=24 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=14 w=15, f=25 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=15 w=19, f=26 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=16 w=82, f=79 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=17 w=944, f=22 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=18 w=993, f=82 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=19 w=1001, f=30 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=20 w=1002, f=33 e=1 d=0 2020-07-06 18:18:36.932+0000: 3273: debug : virEventPollMakePollFDs:401 : Prepare n=21 w=1004, f=83 e=1 d=0 2020-07-06 18:18:36.933+0000: 3273: debug : virEventPollCalculateTimeout:338 : Calculate expiry of 8 timers 2020-07-06 18:18:36.933+0000: 3273: debug : virEventPollCalculateTimeout:346 : Got a timeout scheduled for 1594059521930 2020-07-06 18:18:36.933+0000: 3273: debug : virEventPollCalculateTimeout:359 : Schedule timeout then=1594059521930 now=1594059516933 2020-07-06 18:18:36.933+0000: 3273: debug : virEventPollCalculateTimeout:369 : Timeout at 1594059521930 due in 4997 ms 2020-07-06 18:18:36.933+0000: 3273: info : virEventPollRunOnce:640 : EVENT_POLL_RUN: nhandles=21 timeout=4997 The ceph itself seems to work, i.e. I can execute ceph -s / rbd -p <pool> ls -l, etc. That produces the output. It's just the libvirt seems to be no joy. The version of libvirt installed is: libvirt-bin 4.0.0-1ubuntu8.1 Any idea how I can make ceph Octopus to play nicely with libvirt?
