Re: DL170e G6 iLO, unable to boot from virtual media

Hello, finally the problem has been solved.

We managed to make the virtual media feature to work from a Windows Server machine located in the same datacenter, thereby skipping all the network.

Seems like the problem could be related to blocked ports AND incompatible OS (we've been using ubuntu throughout the test).

Also, keep in mind that the ISO is successfully mounted only if its name changes to the ip address of your local machine in the virtual media applet (see screenshot).

Also, on our Windows Server we had to mount the ISO TWICE for it to show as correctly mounted.

One more thing: if you're using LO100 you have to use java 1.4.2_13 (exactly that version, not any other, even minor), else the virtual media will keep silently disconnecting.

By the way, the correct ports to open are 5901 TCP and UDP, as stated in HP official bulletin:

You should be able to image your disks from a snapshot:

First you wil need to make sure the Vm is not running:
virsh suspend vm
Now you can create a snapshot make sure to adjust the size 100M and the name vm-root-snapshot to your own needs.
lvcreate -L 100M -n vm-root-snapshot -s /dev/sysvg/vm-root
After this you can start the VM again.
virsh resume vm

Now that you have the snapshot you can create the image and delete the snapshot:
dd if=/dev/mapper/sysvg-vm--root--snapshot of=/tmp/vm-root.img bs=1M
lvremove /dev/mapper/sysvg-vm--root--snapshot

The image can be copied to the new server and imported to the LVM on the new server with dd
dd if=/tmp/vm-root.img of=/dev/mapper/sysvg-vm--root bs=1M

Also don't forget to import your XML file.
virsh define /path/to/vm.xml
