Hi Sven,
Please let me know which VDSM hook can be used for the same,is =

I don't know any hook that does this, it should be relatively = simple, though. Maybe someone else can assist, CC'ing Dan:
Do you know of a hook that manipulates the emulated CPU model?
Within the Vdsm code tree, only faqemu does that (and it only = drops, causing qemu to do its best). You can build on top of faqemu to = set to your favorite guest cpu.
However, I think that Engine was once capable of setting a = specific cpuType - is it still possible without hacking its DB, Arik?
I'm not sure what do you actually mean hide what from whom? the guest sees particular CPU, there's nothing like "Virtual xyz", = it either sees flags matching e.g. Nehalem or not. You can select = different CPU at the cluster level if you wish, and that's what the = guest will see, regardless what your host has
faqemu is changing the configured CPU type to fully emulated CPU=85I = don't think you meant that...
I guess he refers to the cpu_model mentioned here: = http://docs.openstack.org/trunk/config-reference/content/list-of-compute-c= onfig-options.html =20 yes, that's what we have at cluster level and there is an RFE for =

But I still do not see the benefit of "faking" a certain cpu model.
=20 there is no faking, it is always real for the guest. so yes, you can make it look(and actually perform) less capable so you = can migrate across heterogenous hosts; or make it less capable just if = you wish so, but that's it. =20 Thanks, michal =20
