  • Did you closed both VM, and simply rebooted the server first ? – yagmoth555 Oct 16 '15 at 13:03
  • @ yagmoth555 , I rebooted sever still XE-command sill frorzen and only one vm is automatically up and ............................. I can see only one vm by domain_lis command ....................... xencenter is not connecting – Jobish Jose Oct 16 '15 at 14:42
  • start by doing a df -m via the console/ssh on the host, is the disk is full ? – yagmoth555 Oct 16 '15 at 15:56
  • disk is not full only 79% ................... – Jobish Jose Oct 16 '15 at 16:08
  • Your state.db is probably corrupt then. cd /var/xapi, check the file timestamp, if old, it's corrupt. if so, mv state.db state.db_bak, after service xapi restart – yagmoth555 Oct 16 '15 at 16:34

xe toolstack-restart will always cut your xencenter connection. (but the vm continue to run correctly on the host)

Please log in normal console (iDRAC, iLO, etc..), as that mean your XAPI can't restart and your server state is unknown.

I would check with dmesg or in /var/log for xensource.log for any errors.

  • Brother , Thanks for your replay .. ,,,,, I can acess server through ssh and i can access all vm ........ can you explain little bit more i am not familiar in xenserver .... – Jobish Jose Oct 15 '15 at 20:34
  • @JobishJose The toolstack-restart cut the comminucation with the console (but the vm continue to work), but usually you can reconnect back some minute later with xencenter when the service restart. I would check dmesg to check if a error occurred somewhere. (or xensource.log in /var/log) – yagmoth555 Oct 15 '15 at 20:45
