Host lock up in F11

[Andrés García]

Hi,

I sometimes have my F11 virtual machine server crash with leaving me 
with nothing but
blinking keyboard lights.

Searching for a solution I found this:

Could someone please tell me, if the post is right and whether the 
problem has been solved
in F12.

Thanks,
Andres

This sounds like:

https://bugzilla.redhat.com/483532

I can't find any reference to it being fixed, but it may just have gone
away with newer kernels

Best bet is probably to hook up a serial console so you can get the full
oops info

Host lock up in F12

[Andrés García]

Hi,

I have found a way to consistently lock up a F12 host.

I had three guests, another F12 and two windows ones. I added another 
with the lastest
Mandriva x64, configured as 'kernel newer that 2.6.25 with virtio', it 
installed fined and
everything seemed to be all right.

To test what would happen  I then went to a terminal a typed 'reboot'.

On powerin on, the host would allway lock up, fortunatley it gave enough 
time to disable
Mandriva starting on boot and now it works.

Does that ring a bell? Is there a way have a guest boot five minutes 
after boot?

You mean like this?

Problem is I don't have a serial cable, I will have to check if the 
electronics store has one.

Thanks,
Andres

Yeah, it sounds similar to https://bugzilla.redhat.com/528245

Could you also try making your network connection available to all
users? See comment #7

I don't have wireless like in that report but I do have two network 
cards, eth0 for the host
and eth1 bridged for the guests.

So to try it I added NM_CONTROLLED=yes for eth0 and NM_CONTROLLED=no
for eth1 and br1, activated NetworkManager back and made sure that eth0 was
available to all users.

Booting Mandriva kept locking the host, so I created another mandriva 
virtual machine
except this time I configured it as 'kernel 2.6.x', no virtio, and now 
the host and the guests
seems to boot at without a problem.

Andres
