hi,
I use xl toolstack to manage vms on a Xen machine, and also pass some custom parameters when creating a vm, for example:
xl create vm.cfg ' param="xyz" '
Documentation on create subcommand in the xl man page describes the 'key=value' options as
key=value It is possible to pass key=value pairs on the command line to provide options as if they were written in the configuration file; these override whatever is in the configfile.
I am moving to libvirt for vm management. How I can pass those extra parameters using libvirt?
I'm not aware of similar functionality in libvirt. You would need to customize the domXML before feeding it to 'virsh create'.
Qemu domains have that ability, via an XML namespace that adds <qemu:commandline>: http://libvirt.org/drvqemu.html#qemucommand but no one has yet implemented that for Xen domains. If you want to add it, the src/qemu code would be the obvious starting point to copy from. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
