I am trying something similar to http://wiki.libvirt.org/page/QEMUSwitchToLibvirt#-s . This is my xml file :

<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
    <type arch='x86_64' machine='rhel5.4.0'>hvm</type>
    <boot dev='hd'/>
  <clock offset='utc'>
    <timer name='pit' tickpolicy='delay'/>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' cache='none'/>
      <source file='/root/incremental.img'/>
      <target dev='hda' bus='ide'/>
      <address type='drive' controller='0' bus='0' unit='0'/>
    <controller type='ide' index='0'/>
    <interface type='bridge'>
      <mac address='00:16:3e:98:78:04'/>
      <source bridge='br0'/>
    <serial type='pty'>
      <target port='0'/>
    <console type='pty'>
      <target port='0'/>
    <input type='mouse' bus='ps2'/>
        <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
          <model type='cirrus' vram='9216' heads='1'/>

        <qemu:arg value='-s'/>

I start the VM from this xml file. Now When I do "ps aux | grep rubis" , I get :

root 13496 59.1 3.5 1266168 292112 ? Sl 16:50 0:23 /usr/libexec/qemu-kvm -S -M rhel5.4.0 -m 1024 -smp 2,sockets=2,cores=1,threads=1 -name rubis_ws -uuid 1a474ca9-604f-aceb-2fed-792fe1e9f900 -monitor unix:/var/lib/libvirt/qemu/rubis_ws.monitor,server,nowait -no-kvm-pit-reinjection -boot c -drive file=/root/incremental.img,if=ide,bus=0,unit=0,boot=on,format=qcow2,cache=none -net nic,macaddr=00:16:3e:98:78:04,vlan=0 -net tap,fd=18,vlan=0 -serial pty -parallel none -usb -vnc -k en-us -vga cirrus -balloon virtio

root 13531 0.0 0.0 61192 760 pts/5 S+ 16:51 0:00 grep rubis

I cannot find the -s in that command . Can you please let me know whether I am making any mistake. I have been stuck with this for a long time without knowing how to solve it. My ultimate aim is to make this command argument work and use it for -incoming tag using qemu command line argument with libvirt.

Thanks for your help.

on what distro are you doing this? Might be that your libvirt build is too old to support this option

  • I see. Im using libvirt 0.8.2 .Its not supported in this distro ?
