10-stable / vmrc snapshot: installing centos does not quite work

[mathiasp]

Hi Michael,

thanks for vmrc.

I'm a first-time user of vmrc and bhyve ;) , and try to set up a centos image.

Choosing the centos65amd64iso, creating configuration and directories seems to work fine.

I'm dropped into the shell with a notice like
use /usr/local/etc/rc.d/vm onestart zimbra-centos2 to start your image...

Sadly, that drops me into a blank grub window...

Looking at the config file, it seems the machine is not started as iso.

So either the installation did not happen before, or the notice forgets to tell me how to boot the cdrom.

I'm now fumbling with booting manually - have to google a bit about grub...

Ask away if you need more information.

Cheers, Mathias

Oh, the notice told me to use

/usr/local/etc/rc.d/vm oneiso zimbra-centos2

which I did. Guess something is not working after all ;)

I could install it, just using the grub commands from the config file.
BTW: the ascii graphics where horrible, I could just barely make it through the installer. I'm using tmux via ssh, and tips on how one could get the correct chars?

It still doesn't boot with service vm onestart,
It starts and works with manual grub commands

This is the commandline I'm seeing with ps auxwww:

Here is the vmrc output as far as I can see:

Is it intended that there is only a loopback device?

          RX bytes:600 (600.0 b)  TX bytes:600 (600.0 b)

Shouldn't this bridged device show up somewhere?

# cat ifconfig_cmd.sh 
ifconfig tap8000 create
ifconfig bridge0 addm tap8000 up

Seems I have to learn more about bhyve - I had hoped vmrc would hand hold me a bit more :)

Lazy me :)

OK, the grub / booting issue is documented in #8, and I now know that I do have a network card, I just needed ifconfig -a, linux doesn't show network cards that are down by default, duh... Maybe something worth documenting for linux noobs like me ;)

And giving tips how to configure bridged networking might also be helpful - it's my first time, and currently I have no idea how to give this virtual machine it's own ip ;)

Were you able to put the full GRUB command in the configuration file? I
got a complaint about unmatched )'s and hope to experiment later today.

Any chance you are on the bhyve IRC channel?

I may have questions as I read through your work.
