Hello there,
I have a VM installed in Fedora 10 with the virt-manager
gui. Its
great! I love the fact I can mount disks so guest and host can both see
them.
But..I created it with 1-2GB ram (from my total 4), and it defaults to 1GB.
That works. If I increase it to 2 I start to see weird crashes in the host.
How can I migrate this system to having always 2GB please?
---and safely!
Thank you,
Bill

Hi Mark,
Yes, you are correct. Trouble is it is a pig to do. I have to
actually use the machine
to generate a hang, and when I do who knows what it costs me.
But I''ll try.
Would you think virt-manager is the culprit? I see nothing suspicious
in the log file
there. Or kvm? or libvirt?

OK,
well after a couple of hours of running ''valgrind'' on a
massive
piece of code I have had no problem at all.
Maybe something has change - but it is not in libvirt/kvm, there
have been no fedora changes there in the last few days. Unless it is the
guest, but that seems unlikely - it should not be allowed out!

Or kvm? or libvirt?It sounds like it''s most likely a kvm bug - if it causes a host kernel oops, then the most important thing is to get the full trace of that oops. Cheers, Mark.
