IVM:Adding boot entry in EFI for guest OS

[amit mehta_2]

Hi,

After installing VM bundle T2767AC on one of my IA machine,i have created one guest(vguest1) and have installed os(11iv2) for vguest1 from DVD on SAN disk connected to same host(hpia7).
Now i guess i need to setup a boot entry in EFI for vguest1.How should i go about doing this ?

Some logs:

Please clarify what you are after.
You do NOT set a boot entry in the EFI of the HOST server. This is done in the Virtual EFI of teh guest machine, at the time of installation.
Please read the manuals fo rIntegrity Virtual Machines at:
http://docs.hp.com/en/vse.html#HP%20Integrity%20Virtual%20Machines

Hi Melvyn,

Thanks a ton for jumping here.

Now,to access the guest console,i have added users as:

root@hpia7/ >passwd guest1
Changing password for guest1

Now while trying to access the guest(vguest1) console through telnet,i get the following error message:

root@hpia7/ >telnet vguest1
vguest1: Unknown host


~amit

[Torsten.]

root@hpia7/ >telnet vguest1
vguest1: Unknown host


You probably doesn't have an entry in the /etc/hosts file of the VMHost.

[amit mehta_2]

Oops,my mistake,

Thanks Tosten,i did that and now i am able to ping the guest(vgeust1)

Now while trying to log on the guest(vguest1)
with the username guest1(as created previously) i am getting authentication error.Though i am providing the correct password.

root@hpia7/ >telnet vguest1

User Access Verification

~amit

[Torsten.]

The account guest1 you created earlier is for **console** access, this user can access the virtual MP for this HPVM.

This is not a valid user for use with telnet.

"A captive virtual console account is a special-purpose user account created on the VM Host for each guest administrator or operator. These types of user accounts use /opt/hpvm/bin/hpvmconsole for a shell, and the desired guest's per-guest directory for a
home directory. For virtual console access, the account also requires a password, and access to its associated guest."


See chapter "9.2 Creating Guest Administrators and Operators" in the manual.


Telnet to the HPVM, logon with root account and create user accounts.

[Torsten.]

From the manual:

The following is an example session of remote access to the compass1 virtual console on the
VM Host myhost:

# telnet compass1
-------


IMHO this must be

# telnet myhost
(this is the VMHost)

Login with the guest1 account (configured as a user on the VMHost) and the hpvmconsole will start as the login shell.

Try this, I can't.

[melvyn burnard]

Again I suggest, Read the Manual

It is trying to boot from the Disk Media.
As mentioned before i have installed os(11iv2) for guest (vguest1) on SAN disk(external disk ),
so how can i ask the guest(vguest1) to boot from it ?

[Torsten.]

Did you install from the vMP console interface?

Your only valid filesystem is the install CD-ROM:

fs0 : Acpi(PNP0A03,0)/Pci(1|0)/Scsi(Pun1,Lun0)/CDROM(Entry0)


I'm not sure what you did so far...

[amit mehta_2]

Hi Torsten,

After carefully reading the manuals,though
there is so much yet to read and understand,i tried setting up the virtual machines from scratch.

After creating the VM(Virtual Machine),i went to its console(hpvmconsole -Pvguest1) and tried installing the VM for the first time from lanboot.(Before this i had to set the PC to ON)



Now during the installation i get the message saying,
"There were no disks found during the IO scan. You will need to
correct any hardware problems and either use the "Scan Again" button,
or reboot and try again. "

How can i add some disks to this VM(vguest1)
I tried with 'hpvmmodify' but seems that i am not providing the correct HW path.

If you really want to assign the disk, try

root@hpia7/ >hpvmmodify -A -Pvguest1 -m disk:scsi::disk:/dev/rdsk/c4t2d0

[amit mehta_2]

Hi Torsten,

while trying to do so,i am getting the following error message:

i am trying to install OS for guest machine and as i have plenty of san disks,therefore i plan to do so on SAN disk.

~amit

[Torsten.]

Please read the chapter

"7.2.2.3.2 Virtual LvDisks"

in the manual. On a SAN without using a multipath software solution you should consider to use "LvDisks" (logical volumes under LVM or VxVM control) as backing store for the guests.

Hi Torsten,

While trying to export disk to the guest VM(vguest1) i get the following warning message:

The warning message seems to be due to some configuration problem.

[Torsten.]

Looks like the disk is already under VxVM control from the VMHost point of view and now you are using the same disk for the HPVM.

As mentioned before, consider to use a logical volume instead of the whole disk.

Without a multipath extension, you have only a single path to the disk for the guest.

If this path fails, your guest will fail too.

To workaround this, use the multipath cabability provided by the volume manager and use a logical volume instead.
