Hello,
I use Xen-API to manage may virtual machines. But sometimes something
goes wrong and I gen an undestroyable VM.
"xm list" shows no domain id for this virtual machine, so, I guess, it
doesn't take hardware resources.
# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 459 4 r----- 508.0
vm-1 160 1 0.3
That seems normal for any domain which is created with Xen-API and not running.
But a "normal" domain can be destroyed with Xen-API VM.destroy() call. When
xm is configured to use Xen-API it shows:
# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 459 4 r----- 0.0
vm-1 -1 0 0 ------ 0.0
# xm destroy vm-1
# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 459 4 r----- 0.0
vm-1 -1 0 0 ------ 0.0
The same with my own test script:
Logging-in to the Xen-API server... OK

How can I get rid of such domain without rebooting the machine or restarting
xend?
Greets,
