Hi,
I am seeing a problem with a earlier working domain configuration. Here
is the domain xml file. I am not getting the virsh console now. I am
trying this on RHEL 6.0.
Here is the list of steps that I am using:
[root@krm1 test]# virsh define vmtest.xml
Domain vmtest3 defined from vmtest.xml
[root@krm1 test]# virsh start vmtest3
Domain vmtest3 started
[root@krm1 test]# virsh console vmtest3
Connected to domain vmtest3
Escape character is ^]
[root@krm1 test]# virsh dominfo vmtest3
Id: 2
Name: vmtest3
UUID: 2b38ff93-1bc6-c78c-1ed8-ffb936c86dac
OS Type: hvm
State: running
CPU(s): 1
CPU time: 17.3s
Max memory: 524288 kB
Used memory: 524288 kB
Persistent: yes
Autostart: disable
[root@krm1 test]#
The state of the domain shows running. One more thing that i noted was
that qemu-kvm is consuming 100% of the cpu. So not sure if the qemu-kvm
has started properly. I am not sure how to debug the issue. Would
appreciate some help on this.
Some more information:
I have attached following file /var/log/libvirt/qemu/vmtest3.log
Executing the following command on the bash works fine and the VM comes up:
/usr/libexec/qemu-kvm -M rhel6.0.0 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1
-drive file=/home/bharata/cgroup-scalability/test/test.qcow2 -nographic
While executing the command in the vmtest3.log, the VM does not come at
all.
Here is the domain xml:
<domain type='kvm'>
<name>vmtest3</name>
<memory>524288</memory>
<vcpu>1</vcpu>
<os>
<type arch='i686'>hvm</type>
<boot dev='hd'/>
</os>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/home/bharata/cgroup-scalability/test/test.qcow2'/>
<target dev='hda' bus='ide'/>
</disk>
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target port='0'/>
</console>
</devices>
</domain>
Thanks,
Nikunj
