im sure you would have tried these steps ... , can you try these steps ..
xenserver is in maintenance mode in xencenter - > can you try to "right click" on the host in maintenance mode in xencenter and try to "exit maintenance mode" what happens ... if it does not work -- > 1. xe-tool-stack restart 2. cat /etc/xensoource/pool.conf - does it have the right pool master ? also xenserver has a great feature ... before upgrading xenserver to the next version , it makes a backup copy of the previous install , if your upgrade is broken you can always roll back from the backup. thanks prashant On Sun, Jul 5, 2015 at 9:57 AM, Sonali Jadhav <[email protected]> wrote: > Anyone? > > Sent from my Sony Xperia™ smartphone > > > ---- Sonali Jadhav wrote ---- > > Hi, > > two days back I upgraded ACS from 4.4.2 to 4.5.1.
