I'm currently checking the VI API to see where to gather the
information for dump-xml, but it seems one needs to read most of it
from the .vmx file of a virtual machine located on the host. Luckily
all files of a virtual machine are readable via HTTP:
http://example-esx-host.com/folder/... So the .vmx file is easily
accessible using libcurl.
Luckily (again) there is some unofficial documentation about the VMX
format available: http://www.sanbarrow.com/vmx.html
Yeah the VMX file format is quite straightforward to read / write.
We already do a similar thing for Xen's configs in /etc/xen - the
raw config file parsing code for that is in src/conf.c, and the code
to convert XML <-> XM Config is in src/xm_internal.c
Within the next few days I'll post a proposal on how to map a .vmx
file into the libvirt xml representation.
For create-xml the ESX driver would need to write a .vmx file to the
ESX host, because the .vmx file is essential to create a virtual
machine. Luckily (once again) the ESX host allows putting files to
http://example-esx-host.com/folder/... via HTTP.
Again, sounds pretty straightforward & a reasonable way to go.
