Hi,
I have the following domains on my machine, each of them have the
graphics tags in them:
virsh list --all
Id Name State
----------------------------------
- graphics_domain2 shut off
- testdom1 shut off
Here is the xml files that I used to create the guests. The only common
thing in them is the uuid.
SAP1.xml :
<domain type='kvm'>
<name>testdom1</name>
<uuid>6fa1cd59-0c71-483d-bd63-7a6a3f53d180</uuid>
<memory>131072</memory>
<currentMemory>131072</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686' machine='pc'>hvm</type>
<boot dev='hd'/>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/bin/qemu</emulator>
<disk type='file' device='disk'>
<source file='/tmp/myimage'/>
<target dev='hda' bus='ide'/>
</disk>
<interface type='network'>
<mac address='11:22:33:aa:bb:cc'/>
<source network='test_default'/>
</interface>
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='5901' keymap='en-us'/>
</devices>
</domain>
SAP2.xml :
<domain type='kvm'>
<name>graphics_domain2</name>
<uuid>6fa1cd59-0c71-483d-bd63-7a6a3f53d180</uuid>
<memory>131072</memory>
<currentMemory>131072</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686' machine='pc'>hvm</type>
<boot dev='hd'/>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/bin/qemu</emulator>
<disk type='file' device='disk'>

<target dev='hda' bus='ide'/>

</interface>
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='5999' keymap='en-us'/>
</devices>
</domain>
wbemcli ein
'http://root:passwd@localhost/root/virt:KVM_KVMRedirectionSAP' -nl
localhost:5988/root/virt:KVM_KVMRedirectionSAP.CreationClassName="KVM_KVMRedirectionSAP",Name="5901:-1",SystemCreationClassName="KVM_ComputerSystem",SystemName="testdom1"
localhost:5988/root/virt:KVM_KVMRedirectionSAP.CreationClassName="KVM_KVMRedirectionSAP",Name="5901:-1",SystemCreationClassName="KVM_ComputerSystem",SystemName="testdom1"
But the EnumerateInstance of the ComputerSystem will give the correct
results:
wbemcli ein 'http://root:passwd@localhost/root/virt:KVM_ComputerSystem' -nl
localhost:5988/root/virt:KVM_ComputerSystem.CreationClassName="KVM_ComputerSystem",Name="testdom1"
localhost:5988/root/virt:KVM_ComputerSystem.CreationClassName="KVM_ComputerSystem",Name="graphics_domain2"
This symptoms is not seen with Xen, where the xml contains the same UUID.
I want to know why is this kind of difference in the behaviour and
whether this is expected.

This looks like a libvirt bug. The UUID of a guest should be unique -
each guest should have a different one. If you define an XML with the
UUID of another guest, the guest should be updated. In this case, a new
guest is defined, which is incorrect behavior.
If you modify your XMLs so that the guest name of each is the same, then
you will only see one guest.

Ok ! One more thing, When we define a guest using the virsh and
enumerate KVMRedirectionSAP , the lport of the ElementName/Name will
contain the port value in the used in the XML file and the looks
something like 5900: -1 (where 5900 is the port value used in the XML).
But defining the guest using the DefineSystem() returns a value of -1 :
-1 in the ElementName/Name.
The DMTF - 1076 does not specify how the value of ElementName/Name filed
should be. Is this expected behavior ?
If you modify your XMLs so that the guest name of each is the same,
then you will only see one guest.

Are you specifying a value of 5900 in your XML? Does it look like:
<graphics type='vnc' port='5900' autoport='yes'
keymap='en-us'/>
When you define the guest using DefineSystem(), what are you setting the
Address attribute of the GraphicsRASD to?
The Address attribute is in the form of: Address="127.0.0.1:-1" The
portion after the : is the port number. If a value isn't supplied for
the Address, the default is to use -1.
