hi everybody, I'm have a huge problem!
I have 2 hosts, host 1 with xen 3.3.1 and host 2 with xen 3.4.2. Host 1 was running some guests for some days and today morning all guests crashed, xm non-responsive and some minutes after the entire host crashed, I had to do a cold reboot.
I tried to start guests on host 2, when I started the second guest same problem. The difference is the host 1 after reboot xend started normally and hosts 2 xend is not starting anymore. So... actually I have 2 big problem, (1) instability (2) xend not working after crashed.
( This is not the first time it happened... the both problems! )
Any ideias?
Host 1 - instability
