[libvirt] libvirt equivalent config for a kvm command line
Hi,
I had been running kvm in a previous version of Ubuntu with the
following command line:
/usr/bin/kvm
-hda /mnt/kvm/vm-images-work/nanobsd.img
-net nic,vlan=26,macaddr=52:54:00:12:34:26 -net tap,vlan=26,ifname=tap26
-net nic,vlan=27,macaddr=52:54:00:12:34:27 -net tap,vlan=27,ifname=tap27
-net nic,vlan=28,macaddr=52:54:00:12:34:28 -net tap,vlan=28,ifname=tap28
-m 640 -vnc :26 -usbdevice tablet
The vm shows couple if lines in console and then redirects rest of the
output to serial console. I can see that in ctrl-alt-3 of vncviewer
ctrl-alt-2 gives access to emulation console and 4 gives access to
parallel console.
After upgrading to latest Intrepid Ibex I decided to move to using
virsh to manage my vms. For the above vm I am using the following xml
file.
<domain type='kvm'>
<name>nanobsd</name>
<memory>262144</memory>
<currentMemory>262144</currentMemory>
<vcpu>1</vcpu>
<os>
<type>hvm</type>
<boot dev='hd'/>
</os>
<features>
<acpi/>
</features>
<clock offset='localtime'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/bin/kvm</emulator>
<disk type='file' device='disk'>
<source file='/mnt/kvm/vm-images-work/nanotest.img'/>
<target dev='hda' bus='ide'/>
</disk>
<interface type='bridge'>
<mac address='52:54:00:12:34:31'/>
<source bridge='br0'/>
</interface>
<interface type='bridge'>
<mac address='52:54:00:12:34:32'/>
<source bridge='br0'/>
</interface>
<interface type='bridge'>
<mac address='52:54:00:12:34:33'/>
<source bridge='br0'/>
</interface>
<serial type='vc'>
<target port='2'/>
</serial>
<console type='pty'>
<target port='0'/>
</console>
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='5931' listen='192.168.3.3'/>
</devices>
</domain>
Which produces the following command line.
/usr/bin/kvm -S -M pc -m 256 -smp 1 -name nanobsd -monitor pty
-localtime -boot c
-drive file=/mnt/kvm/vm-images-work/nanotest.img,if=ide,index=0,boot=on
-net nic,macaddr=52:54:00:12:34:31,vlan=0 -net
tap,fd=28,script=,vlan=0,ifname=vnet5
-net nic,macaddr=52:54:00:12:34:32,vlan=1 -net
tap,fd=29,script=,vlan=1,ifname=vnet6
-net nic,macaddr=52:54:00:12:34:33,vlan=2 -net
tap,fd=30,script=,vlan=2,ifname=vnet7
-serial vc -parallel none -usb -vnc 192.168.3.3:31
Problem with this configuration is that the screen freezes after
couple of minuets of booting, I am not sure if this is the problem
with the serial console or actual execution. I can see the serial
console in ctrl-alt-2, but the window size changes. The image works
perfectly in normal PC as well as if I use the previous command line.
I guess I am missing some thing here, but I would be very happy if I
can get the old behaviour back :)
