Hi libirt-list,
I am attempting to migrate from Xen->KVM and am having a little trouble
understanding the new vnet<X> interface numbering scheme and how to use it to
collect statistics of the interface using the interfaceStats() function.
In Xen, the ID for a given domain was know, and a corresponding vif<ID>.0
interface was brought up so it was easy to grab the stats (amongst other
things).
Under my new KVM config I've realised that vnet<X> is brought up in a 'first
free' fashion as opposed to a counter in the Xen case. This leaves me
scratching my head a little bit, say I have a domain which has ended up with ID
= 8, but may for instance have network 'vnet1' associated with it. I'm not sure
how I can determine any association between the domain & which interface
belongs to it! (e.g. a call to domain.interfaceStats() requires the correct
network interface as a parameter).
Surely I must be missing something here? Anyone have any advice/workaround for
this situation? Ideally I would like to either be able to hardcode vnet-labels
in the XML description (tried but it's ignored), or otherwise keep vnet
numbering in sync with domain ID.
Thanks in advance,
Ravi
