Toni, please understand that it looks like you're the only one on this
planet to hit the issues you describe with kvm. #569990 and #568293 -
both of them are, well, unreproduceable (I mean the last parts of them).
Seriously, it was quite some time ago when I saw kvm behaving like this
having issues in places where it just works since long time...
I can't do anything with this unless I can reproduce the issues. Or
maybe you provide access to your system to me. Or else I'll just mark
the bugs as 'unreproduceable'.
I'm not a developer of qemu or kvm, I don't know much internals, but
I've some pretty good experience in this area (I think I've hit every
kvm's bug ever existed, -- that's why I wished to step in to manage it
in Debian), and I've seen many various problematic situations with it
too -- #kvm @FREENODE had alot of them.
What you describe just does not fit in my mind. That's the reason of
my quite harsh tone when I replied to bugs mentioned above... It's
sorta like discovering bugs in cat(1) (lockups, opening wrong files
etc) which worked for many people before...
Please don't get me wrong - I want this mess to be sorted out somehow,
but - in short - I can't believe it unless I'll see it with my own
By the way, have you tried to update BIOS and upgrade the CPU you
have? If memory serves me right, you've Athlon X2 64 4400+, and
maybe that's the problematic one too... I'll try kvm on my old
Acer Aspice 9300 (circa 2005 or so) with a dual-core Duron, but
I know I've run KVM on it before and it worked just fine...
