Re: virt-install doesn't reboot rhel6/7 VMs after install

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'll try that, thank you!

Out of curiosity, why would other OSes (like all Windows installs) restart properly?

Sorry for the late response. I think the issue is that virt-viewer is failing
to launch, probably because this is done on a TTY or over SSH.

The default virt-install invocation kind of depends on virt-viewer running to
detect when the VM starts up and shuts down. However you can force it to not
work that way with --noautoconsole (don't launch virt-viewer) and --wait -1
(wait indefinitely for the VM to shutdown, then restart it)

Hi all,

     I've noticed that, for reasons I am not entirely sure of
(though may exist
and be valid), newly provisioned EL6 and EL7 VMs stay off after
pressing
"reboot" at the end of the OS install (--os-variant rhel*). I've
seen this
behaviour on RHEL/CentOS 6.x and various recent Fedoras. Note that
when I
install other OSes, the VM reboots properly.

     Why would this be? Is this designed behaviour? Installing the
same on
bare-iron nodes reboots properly.


The VM should be restarting... can you show an example command line
and full
virt-install --debug output? Make sure you aren't passing --noreboot
or --wait
timeout that is expiring.

The way it's supposed to work is that the VM fully shuts down,
virt-install
changes the VM configuration to boot off the now installed disk, and
restarts
the VM. It does this by telling VM to shutdown rather than perform a
soft
reboot with <on_reboot>destroy</on_reboot> in the VM XML. It does
this for all
VM installs regardless of the OS.

When the VM shuts down after install, virt-install should update the
config,
restart the VM, and exit. But clearly that's failing here

Here is an example install which showed the problem. It is very
similar to how
I do all my EL6/EL7 installs (save for sometimes installing from
PXE/http):

virt-install --connect qemu:///system \
    --name an-a03n01 \
    --ram 2048 \
    --arch x86_64 \
    --vcpus 2 \
    --cdrom /mnt/usb/VMs/files/CentOS-7.0-1406-x86_64-Everything.iso \
    --os-variant rhel7 \
    --network bridge=virbr0,model=virtio \
    --network bridge=virbr0,model=virtio \
    --network bridge=virbr0,model=virtio \
    --network bridge=virbr0,model=virtio \
    --network bridge=virbr0,model=virtio \
    --network bridge=virbr0,model=virtio \
    --disk path=/mnt/usb/VMs/images/an-a03n01.img,bus=virtio,size=40 \
    --graphics vnc


I just tried a centos 7 install from cdrom with a nearly identical
command
line using stock f20 host, and virt-install rebooted the guest
correctly at
the end of the VM install. So you'll need to provide the virt-install
--debug
output of a failing invocation so I can see what's going wrong

Thanks,
Cole

OK, I will try to get that to you later today or tomorrow. Thanks!

Hi,

   Sorry for the lag, got inundated with work.

   I ran a fresh install today on a CentOS 6.5 host, installing CentOS 6.5,
using '--debug' and, as expected, it did not reboot. I manually booted it
after about a minute of waiting.

Provision script:
======
lvremove -f /dev/c01n01_vg0/vm18-striker_0
lvcreate -L 35GiB -n vm18-striker_0 c01n01_vg0

   --name vm18-striker \
   --ram 2048 \
   --arch x86_64 \
   --vcpus 2 \
   --cdrom '/shared/files/CentOS-6.5-x86_64-bin-DVD1.iso' \
   --os-variant rhel6 \
   --video cirrus \
   --network bridge=vbr2,model=virtio \
   --disk path=/dev/c01n01_vg0/vm18-striker_0,bus=virtio \
