I cant put host in maintenance mode before, because the host-egnie is a VM
inside the single host.
... unfortunately the shutdown problem persist ... :-(

Re: [ovirt-users] shutdown and kernel panic

[Pavel Gashev]

Luigi,

It’s necessary to put a host into maintenance mode before shutdown.

That panic is a kernel reaction to NMI, which is triggered by hardware 
watchdog, which is set by wdmd daemon, which is used by sanlock. This scheme is 
intended to hardware reset a server if it has lost connection to its storage 
when lock is acquired.

On HP servers it’s necessary to configure watchdog to do hardware reset instead 
of NMI in BIOS settings.

same issue here. I guess now that I read your post that its an HP bug 'somehow' 
(to blame someone).
maybe thats why ovirt asks for fencing interfaces as ilo/imm/ipmi, to hard 
reboot the server in case there's an issue like this.

Hello to all,
I'm just playing with ovirt4, installed on HP server with CentOS 7, and a 
virtual machine  as host engine.
I have a lot of problems with the server shutdown!
The server dosn't power off and will reboot after some "kernel panic" error.

To turn off the ovirt server:
1) Put ovirt in global maintinience (hosted-engine --set-maintenance 
--mode=global)
2) Host engine shutdown and check vm-status
3) Finaly, shutdown server and wait ... wait ... wait
Whats wrong?! -_-

best regards
Luigi F.

[ovirt-users] shutdown and kernel panic

[Luigi Fanton]

Hello to all,
I'm just playing with ovirt4, installed on HP server with CentOS 7, and a
virtual machine  as host engine.
I have a lot of problems with the server shutdown!
The server dosn't power off and will reboot after some "kernel panic" error.

To turn off the ovirt server:
1) Put ovirt in global maintinience (hosted-engine --set-maintenance
--mode=global)
2) Host engine shutdown and check vm-status
3) Finaly, shutdown server and wait ... wait ... wait

Whats wrong?! -_-
