[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Unable to start a domain with no disks
Trying to start a very simple domain with no disk from:
name="x"
memory=128
kernel="/scratch/debian/squeeze/amd64/vmlinuz"
ramdisk="/scratch/debian/squeeze/amd64/initrd.gz"
extra="console=hvc0"
vcpus=1
Results in:
xl: libxl_event.c:1522: libxl__ao_complete_check_progress_reports:
Assertion `ao->in_initiator' failed.
if I try to autoconnnect the console (ie. xl cr -c).
If I don't try and auto connect to the console then everything is fine
and I can subsequently use "xl cons" to connect.
Backtrace is:
xl: libxl_event.c:1522: libxl__ao_complete_check_progress_reports:
Assertion `ao->in_initiator' failed.
Program received signal SIGABRT, Aborted.
