Hi,
I am trying to start a fully virtualized guest called "full1"
remotely. The connection URI I am using is "xen+ssh://root@dell1/".
(Note that I am able to start/stop/resume/shutdown para-virtualized
guests without any problems with this connection URI.)
The XML definition for the fully virtualized guest is this:
<domain type='xen'>
<name>full1</name>
<os>
<type>hvm</type>
<loader>/usr/lib/xen/boot/hvmloader</loader>
<boot dev='hd'/>
</os>
<memory>1048576</memory>
<vcpu>2</vcpu>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<clock offset='utc'/>
<devices>
<emulator>/usr/lib64/xen/bin/qemu-dm</emulator>
<interface type='bridge'>
<source bridge='xenbr0'/>
<script path='vif-bridge'/>
</interface>
<disk type='file' device='disk'>
<driver name='file'/>
<source file='/xen/full1.img'/>
<target dev='hda'/>
</disk>
<graphics type='vnc' port='5904'/>
</devices>
</domain>
The guest failed to start up and this is what I found in the xend.log
file:

It seems that xend got a string instead of an integer for the vnc port.
I modified the file "image.py" at line 383 from this
ret += ['-vnc', '%d' % vncdisplay]
to this:
ret += ['-vnc', '%s' % vncdisplay]
Restarted xend for the change to take effect and then try starting
the guest again. This time the guest gets created but its state does
not change to "running".
# xm list
Name ID Mem(MiB) VCPUs State
Time(s)
Domain-0 0 451 2 r-----
356.7
full1 88 773 1
------ 0.0
I removed the following vnc line from the xml definition and try again:
<graphics type='vnc' port='5904'/>
The guest gets created but again its state is not "running".
According to xml format documentation the <graphics> tag is required.
At this point I am stumped. Any ideas what else I can try?
cheers,
mengkuan
