Hi,
Using command line I am able to bring up VM
Here is the command:
“/qemu-system-ppc -enable-kvm -m 512M -mem-path
/var/lib/hugetlbfs/pagesize-4MB -nographic -M ppce500v2 -kernel
/boot/uImage-p2020rdb.bin -initrd /

//
/nic,model=virtio -net tap,script=/home/root/qemu-ifup/”
Can anybody let me know the libvirt xml format for above command.
Hi,
I use the command:
$virsh domxml-from-native qemu-argv config
The xml file is as the following:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<name>unnamed</name>

I doubt whether this can work.
BTW, I am working on ppc64 for pseries machine.
The following is my xml configuration.
I think this won't work for ppce500v2, just for reference.
<domain type='kvm'>
<name>nodebug</name>

<memorybacking>

<target dev='sda' bus='scsi'/>

<serial type='pty'>

<console type='pty'>

Thanks~!
