The REST API supports exporting a VM in OVA format.

It sounds like you tried to switch the pool master to a host at a lower xapi level. Had the host that you designated as the new pool master already been patched?

It isn't clear why you are trying to change the master at this time. Can you explain? What is the status of the two hosts that have been patched and rebooted?

@randyrue Was the current master rebooted after being patched?

@MarcVdS The new ISO is already available. See this post for more details.

@DaleDibbadel said in Lost VMs disk after using new SR:

Brought in trunas, set a SR device: /dev/sda, rebooted Dell, now VMs wont start.

Please elaborate on the exact commands that you ran here. Also, you may want to provide the output from lsblk to provide some additional context.

Do you have a backup of your pool metadata?

*** Warning ***

This process and the attached file is only appropriate for restoring towards XAPI 25.27.0. Use this procedure at your own risk.

We recently put together a solution for a customer that had this exact issue. Below are the basic instructions to update freshly installed 8.3 hosts to the set of updates that were available on October 24th, including XAPI 25.27.0 --

• Install XCP-ng 8.3.0 LTS
• scp the attached package_list_for_update.txt to the hosts /root. This file contains package versions from our update repository on October 24th.
• then, on the hosts, from /root: cat package_list_for_update.txt | xargs yum update-to -y
  • This will output a lot of messages saying that this or that package is not found. That's expected. Then it will proceed to install the updates. In my tests, 73 of them.
  • Once the update completes, reboot the host.
• Restore the XAPI metadata
• Restart XAPI
• Verify that XAPI is running.
• Install the remaining updates with yum update -y.
• Reboot

package_list_for_update.txt

Hi,

Can you show us the output from the following command?

xe vdi-param-list uuid=<uuid_of_target_vdi>

If you look at the metadata files on the backup remote, you should see two files: data and metadata.json.

Search either of these for the term "xapi_build", and that should let you know the version of xapi that was active when the backup was made. With this additional information, it should be possible to calculate which updates to apply to your host.

My understanding is that you can only restore metadata to the exact same version of xapi. Does your old pool still exist?

@payback007 Have you tried restoring the metadata prior to installing patches on the host?

@john.c said in "NOT_SUPPORTED_DURING_UPGRADE()" error after yesterday's update:

Please be careful of tenses (past tense etc),

Yeah... I was trying to be helpful, but I was clearly in too much of a hurry.

Mea culpa

s/rebooting/rebooted

Apologies for the miswording on my end.

@archw I'm confused by your recent responses. I asked --

Were the hosts rebooting after the patches were applied?

to which you replied --

Nope!

but then you stated

I always reboot at the conclusion of the update and did as well this time.

Which is correct?

Were the hosts rebooting after the patches were applied?

@kawreh said in Plugins in XO6?:

Isn't there a plugin section in XO6?

Not yet apparently. My guess is that it is "coming soon"

Hi,

Make sure that the XOA VM has been granted the rights to mount the NFS share and create subdirectories.

Hi,

I just responded to your ticket with the steps to update XOA to match your new license.

@dnordmann said in V2V - Stops at 99%:

you mention "xo should say something about " nbdkit logs of ${diskPath} are in /tmp/xo-serverxxxx" do you know where exactly I can pull those? Tried looking under /var/log of XOA but not seeing what you mention.

You can check to XO logs by running the command journalctl -u xo-server -f -n 50 from the CLI of the XOA VM.

Hi @NormHaub,

I suggest that you provide more details so that we can better understand your situation. Are you talking about XOA, XCP-ng, or something else? If XOA, what process are you using to perform the installation?

Dan
