You are looking on the host, right ?

Hello everyone !

I rebuild a new OME appliance with the latest version (4.6)
Dell decided to give this appliance Proxmox, Nutanix and OpenShift compatibility, but no XCP-ng yet... If someone from Dell want to reach out about this, please contact me !

What i did on the rebuild:

• Via live CD
  • add xen-blkfront and xen-netfront driver, and rebuild the initrd
  • change root password
  • activate SSH.
• Via SSH

sed -i -e 's/sda/xvda/g' /opt/dell/omc/utilities/tui/bin/ome_disk_config.sh
sed -i -e 's/sda/xvda/g' /opt/dell/mcsi/appliance/scripts/appliance_resources.sh
bash /mnt/Linux/install.sh # To install XCP-ng tools

As usual, please send a DM if you want the link to the VHD

Feedback is welcome !

(Disclamer: This build is something I create on my free time and to help people who have difficulty running Dell appliances on XCP-ng. I do not guarantee a fully functional appliance, but I do my best to make it work. If you have a support contract with Dell and require official support for OME, please contact Dell and request compatibility with XCP-ng.)

@fluxtor Hi !

First thing to check is dmesg -T, to see if you have any hardware error

Hi ! I think you need to increase XAPI timeout: https://docs.xcp-ng.org/management/manage-locally/api/#modifications

Hi !

PE2950 is very old hardware, I'm not surprised you have some issues with it
Honesty if you can, try to find newer hardware. This generation is also inefficient when looking at the power/performance ratio

@fred974 Hi !

Do you see anything red in XOA check ? (XOA > Support) ?

(BTW you don't have any backup from XOA ? If you have backup, you can just register a new XOA, connect to you remote and restore everything, it will be much simpler)

If I was in your place, I would do:

• Disconnect all USB used as SR
• Reinstall XCP-ng
• if you have only a few VMs, my option would be just to redeploy XOA, REATTACH the SR (not create, REATTACH, be careful, a create will wipe your disk)
  • Recreate VMs, attach the VDI, boot from here
• if you have to many VM, directly after deploying XOA restore your metadata backup, it should be repluging the SR and create PDB at least (but it's been a while since I didn't use the metadata)

In any case, backup everything, especially the VDI (.vhd). If you have the VDI, you can work around with the rest

@nuentes You can reinstall without wiping the SR. Just plug the ISO, it will ask you if you want a clean install or a reinstall

@AlexanderK You're welcome, i'm happy my tests are useful !

@amititre331 Hi !

Can you try the API request by hand (without ansible) to see if it works ?

Also, do you have any errors when running ansible ?

New version release !

A new patch version of the OME appliance is now available

What I changed:

• Add xen-blkfront and xen-netfront driver
• Add guest tool (so RAM/network is reported, soft shutdown is working)
• /dev/sd* is replaced by /dev/xvd*
• Remove grub password
• Change admin and root password
• SSH is now enabled
• SElinux is working correctly
• DHCP is enabled by default

As usual, please send a DM if you want the link to the vhd

Feedback is welcome !

Ok got it, it boots now

I just need to add the tool and ssh support, and the patched version should be available tomorrow

@dreddpenguin Hi !

I didn't see that a new version was released
I'll try to rebuild one from scratch with the latest version, maybe they changed something

If people reading this thread want the last version, please ping me here !

@HeMaN Yes, I just need to reupload it somewhere. I'll send you a DM with the link

@rk9268vc Hi !

i'm confirming the issue:

I'm currently digging, shoud be a missing driver or a harcoded /dev/sda, as usual.....

will report back.

@TheMonkeyBrain Hi !

Let me find the link I had or reupload the file. I'll give it to you via DM ASAP

If you need to uplaod the appliance, you need to replace sda to xvda on this two files:

    /opt/dell/omc/utilities/tui/bin/ome_disk_config.sh
    /opt/dell/mcsi/appliance/scripts/appliance_ressource.sh

@Schmidty86 Try to detach the disk and reattach, it should be xvda in order to be bootable

@rustylh How are you creating your VM ?

@cichy the documentation for the Kvm/proxmox part is really weird with unnecessary steps

Normally you just have to do:

qemu-img convert -O vpc proxmox-disk.qcow2 `uuidgen`.vhd
scp thegenerateduuid.vhd ip.xcp-ng.server:/run/sr-mount/uuid-of-your-SR

Then with XO, create a VM and attach the disk

I really need to find some time to finish the rework of this part of the docs, I'm sorry I didn't do it earlier
