How to remove HPVirtual machine configuration

Adam Noble — Tue, 28 Sep 2010 16:51:41 GMT

Hello,

I decided to make an ignite image of a system which had virtual machines running so that I could clone to another server. The problem is that although the ignite element went rather well I have no idea how to get the virtual machine element working. Clearly it's in a state as the guests have no storage assigned etc. I don't want the guests I just want to use the system. Is there anyway of just deleting all configuration so I can start again.

Thanks

Shalom,

Need more specifics.

You probably need make_net_recovery images of the guest systems in order to replicate them.

I've also successfully duplicated guest systems by running hpvmclone on the new guest system and then using dd through ssh to duplicate an entire system across the network.

Ignite however is the approved tool for doing this.

To delete the configuration of a guest, try hpvmremove

See the man page for specific switches.

Basically, In order to remove a virtual partition, it must be in a down state. After shutdown, we can remove the partition quite simply with vparremove:
first find the partition to remove and make a note;
#vparstatus
then delete;
# vparremove -p vPar1

not sure why vpars are being mentioned here, as you say they ar evirtual machines
just do hpvmremove for each vm
man hpvmremove

The problem is guys in essence I just want to start from scratch. I can't delete individual guests because I can't see them as the configuration is effectively corrupt. I guess I could remove the software and try again but hoped I would not have to. I can't do a hpvmstart for example. It makes sense that I can't do these things I just hoped I would be able to delete all configuration.

I just misunderstood the issue,
you do not need to assign point for this post as you did before.

ok, so is teh HPVM software installed?
what does hpvmstatus report?
If you go look under /var/opt/hpvm, that is where the configuration information is held, so simply removing /var/opt/hpvm/guests/ would remove all definitions that are currently there, although you may also need to remove some other files under /var/opt/hpvm

right Melvyn. I am getting somewhere if slowly. As per your comments I removed software but critivally needed to remove the guest areas so thanks. I then re-installed but hpvm failed to start with the following error:-

RROR: Unable to load module 'rng': No locks available

What I found is this if I copied /stand/last_install/mod/rnd to /stand/current/mod then it would start.

The issue however is when I reboot it does not seem to remain loaded and fails again.
