Summary: "xm list" fails with "Error: (9, 'Bad file descriptor')"
Product: Xen
Version: 3.0.3
Platform: x86-64
OS/Version: Linux-2.6
Status: NEW
Severity: normal
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: jnavratil@xxxxxxxxxxxx
Xen (Oracle VM) installed few weeks ago and we managed to create 6 virtual
machines (both Linux & Windows) and all was OK till today.
I was trying to restart one virtual machine. Shutdown went OK but I can't start
it anymore.
I realized I can't actually manage any of running domains any more. All xm
commands are failing with the same error "Error: (9, 'Bad file descriptor')"
The running domains are unaffected (still accessible). I haven't tried to
reboot the dom0 so far.
Any ideas what should I check now ?
Thank you
Jan
