Hi all,
I'm doing some dev work against the native RHEL/centos 5.5 KVM
installation for maintenance, creation and deletion of virtual guests
using the libvirt API vai the java bindings from a java based web app.
Things in general seem to be working - I can connect to and query the
kvm instance using the libvirt interface and get a list of guests,
pull information about them and stop/start/restart guests.
I'm hitting a bit of an issue with creation of a guest however....
When calling domainDefineXML with XML following the domain XML
specification (with the XML as per a dumpxml on the relevant box) I
get an error creating the guest of:
"internal error unknown lifecycle action restart "
The virsh version information for the host is:
Compiled against library: libvir 0.6.3
Using library: libvir 0.6.3
Using API: QEMU 0.6.3
Running hypervisor: QEMU 0.10.5
I have tried this against my ubuntu system as well with the same error
- that has version:
Compiled against library: libvir 0.7.5
Using library: libvir 0.7.5
Using API: QEMU 0.7.5
Running hypervisor: QEMU 0.12.3
I'm currently using jna 3.2.5 with libvirt 0.4.5 bindings.
The example XML being used is:
<domain type="kvm">
<name>
newguestfomwebapp
</name>
<memory>
512
</memory>
<vcpu>
1
</vcpu>
<os>

<source network="default"/>
<model type="virtio"/>
</interface>
<input type="mouse" bus="ps2"/>
<graphics type="vnc" port="-1" autoport="yes"/>
</devices>
</domain>
If I remove the lifecycle information from the xml I get:
"unknown OS type hvm "
The xml works from the command line with virsh define ...
Anyone seen anything similar or have any ideas?

For the record.... I managed to get this to work in the end and it
appeared to be down to the whitespace.... creating a string
representation of the XML DOM that looked like:
<domain type="kvm">
<name>testserver2002</name>
<memory>512</memory>
<vcpu>1</vcpu>
<os>
<type arch="x86_64" machine="pc-0.11">hvm</type>
<boot dev="hd"/>
</os>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<clock offset="utc"/>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type="file" device="cdrom">
<driver name="qemu" type="raw"/>
<source file="/var/lib/libvirt/images/ISOs/centos5.5-ks.iso"/>
<target dev="hdc" bus="ide"/>
<readonly/>
</disk>
<interface type="network">
<source network="default"/>
<model type="virtio"/>
</interface>
<input type="mouse" bus="ps2"/>
<graphics type="vnc" port="-1" autoport="yes"/>
</devices>
</domain>
Allowed the domain to be created....
