Hi,
Is virsh able to access the VMX config of a virtual machine running on a
esxi host?
I would like to take backups of my virtual machine configs and the
doku section
"Converting from VMware VMX config to domain XML config"
(http://libvirt.org/drvesx.html) comes close to this - but does not tell how
to get access to the vmx file. I would prefer a solution where ssh access to
the esxi host can stay disabled.
best regards, frank

virsh (and libvirt) don't expose the .vmx files, so there is no way to
access them directly trough libvirt. You could get the domain XML
config and convert it to .vmx format using domxml-to-native, but that
doesn't give you the original .vmx file.
The .vmx files are stored in the datastore attached to the ESX(i)
server. You don't need SSH to access the datastore content, An
example, you can access the .vmx file of the virtual machine <vm> on
<esxi-server> stored in <datastore> using this URL:
https://<esxi-server>/folder/<vm>/<vm>.vmx?dcPath=ha-datacenter&dsName=<datastore>
You can also open https://<esxi-server>/folder/ in your web browser
and navigate through the content.

Hi Mathias,
thank you very much - which part of the doku did i miss so i didn't know about the
web-access to the vmx files?

which command gives me the domain xml? dumpxml gives me an error message (expecting an
assignment) - the other xml command need the vmx file i guess ...
btw: do you think libvirt is an option for backup tasks around esxi virtual machines? or
do you know another suitable tool?
regards, frank

Hi Frank,
"In theory" the dumpxml should do that. ie.:
# virsh dumpxml F11test
<domain type='kvm'>
<name>F11test</name>
<uuid>cb3878e2-a1fc-c035-e57c-087e11abcbfe</uuid>
<memory>1048576</memory>
<currentMemory>1048576</currentMemory>
<vcpu>2</vcpu>
<os>
<type arch='x86_64' machine='rhel6.0.0'>hvm</type>
<boot dev='hd'/>
</os>
(...)
<memballoon model='virtio'>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x05'
function='0x0'/>
</memballoon>
</devices>
</domain>
However, it sounds like that's not working for you.
That could be a bug. Would you be ok with trying it again, then pasting
the error message here for us to see?
