Re: [Xen-users] Restarting xend - how?

[Jeff Noxon <jeff@xxxxxxxxxxxxxx>]

Unfortunately, xend becomes unresponsive occasionally.  I can't have
the foresight to stop my domains to prevent this problem.  Also, the
domains need to be running!

I have just discovered that if I remove /var/lib/xend-db/*, xend can be
started again.  I also removed a lockfile.

However, I have only had limited success manipulating domains at that
point.  'xm shutdown' did not work, but destroy did, sort-of.  The domain
lingers around forever with 0 memory allocated to it.  When I start up
my domains again, I get something like this:

# xm list
Name              Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0           0      251    0  r----    116.8
Domain-1           1        0    1  -----      5.6
Domain-10         10        0    1  -----     11.5
Domain-11         11        0    0  -----      2.7

Domain-3           3        0    0  -----      3.4

working-6         17       47    0  -b---      2.2    9617
working-7         18       47    1  -b---      1.9    9618
working-8         19       47    0  -b---      2.5    9619
working-9         20       63    1  -b---      4.1    9620
working-10        21      127    0  -b---     11.3    9621
working-11        22       47    1  -b---      2.3    9622

Also, /etc/init.d/xendomains does not work anymore.  So I still need to
reboot to make things normal again.

Regards,

Jeff
