Jon,
I've attached a snippet from my syslog.
My current status is I reinstalled again and this time tried to install an
ubuntu vm using the instructions here
(http://wiki.xen.org/wiki/Installing_Linux_on_Kronos
<http://wiki.xen.org/wiki/Installing_Linux_on_Kronos> )
I get the same error:
the device disappeared from xenstore (frontend (domid=1 | kind=vbd |
devid=51712); backend (domid=0 | kind=vbd | devid=51712)) ]
In the syslog you'll see some other errors:
May 2 13:27:51 kronos xapi: [ info|kronos|0 thread_zero||watchdog] (Re)starting
xapi...
May 2 13:27:51 kronos xapi: [ warn|kronos|0 thread_zero|server_init
D:2539aa6797cb|startup] task [Checking control domain] exception:
Xenctrl.Error("Unable to open XC interface")
May 2 13:27:51 kronos xapi: [error|kronos|0 thread_zero||xapi] Caught exception
at toplevel: 'Xenctrl.Error("Unable to open XC interface")'
May 2 13:27:51 kronos xcp-fe: 2810 (/usr/sbin/xapi -nowatchdog -writereadyfile
/var/run/xapi_startup.cookie -writ...) exitted with code 2
I always get errors on startup. My process has been to log in and run
/usr/lib/xcp/bin/xe-toolstack-restart which seems to get all of the services
into a functional state.
I'm trying to persevere but I've been at this for a couple of weeks now and
nothing has worked. I don't doubt it's somehow my lack of understanding but I'm
not sure where to turn. Do you think my PC could somehow just not be
compatible? That sounds crazy to me but I'm grasping at straws. Or do some
people have better luck with Ubuntu than Debian?
Thanks,
Dave
