You can have a "composite" job where backup could do delta AND continuous replication at the same time.

Thanks and thanks for your help on irc. You are doing an amazing job!

@olivierlambert said in XCP 8.2 VCPUs-max settings:

You should probably ask on Xen mailing list or in #xen on OFTC IRC

Since the mass exodus from freenode, is the channel on oftc or libera.chat?

I get this message when connecting to OFTC:

@olivierlambert The xen orchestra quick deploy failed from the web. I restarted the toolstack in hopes that it will fix it.

Is there a way to upgrade XCP from 8.0 to 8.2?

@olivierlambert said in I have a xen orchestra that won't respond on the xcp center console.:

I don't understand. XOA isn't running on Ubuntu.

Do you mean Xen Orchestra from the sources?

Sorry, it is a xen orchestra from source. We call it XOA here.

edit: XCP-ng 8.0 is EOL since a bit now. Only 8.2 is supported.

Ok. Our next step will be to upgrade it to 8.2. So I understand that we won't be able to open a ticket.

In the meantime, I will do the xen orchestra proper install from the web.

@olivierlambert said in I have a xen orchestra that won't respond on the xcp center console.:

You can import a fresh XOA then.

Ok, great.

I went ahead and created a new XOA vm in XCP center from the ubuntu 18 template (with a ubuntu 64-bit 20 lts iso) for over an hour. The earlier task of "create vm" is at about 66%, and the start new vm says "cancelled", as the screenshot shows. I have highlighted the two relevant tasks.

I think something is up with the hypervisor. Unfortunately I can not reboot the physical hypervisor until 4am tonight, as we are an ISP and many of our customers have all of their traffic going through the mikrotik RouterOS cloud-hosted-router vm on this server (66 day uptime).

This XCP is 8.0, build date 2020-06-02, DBV 0.0.1.

@olivierlambert said in I have a xen orchestra that won't respond on the xcp center console.:

Have you force restarted it?

Yes. But first I did the polite restart in XCP Center and waited 30 minutes.

I have a xen orchestra that won't respond on the xcp center console. It's at a remote location.

Can I create a new XOA server on it and disable old one with no ill effects? It's not pooled or part of a vapp. Backups have not run since 7/26.

I ran nmap against the common ports, none are open.

Our existing backup (to the QNAP NAS) is a delta backup. I am guessing the backup to the cold spare should be a nightly CR? Or a delta? It will be a nightly backup. But if it's low enough on resources, the backup could be hourly.

I have nightly backups to a qnap nfs share.

I am building a new XCP as a cold spare, where I will mirror the VMs nightly (and leave in a shutdown state).

Should I create a new backup job or make it part of the existing backup job (the existing job is a delta backup and each individual backup finishes in one hour) at roughly 11pm at the latest?

Both servers are on the same switch.

~~I have our main server and I have installed a secondary XCP server on the network. I would like to do a weekly restore of some VMs to the secondary VM and then do a nightly restore of a few specific VMs. My manager doesn't know Xen well enough to use a storage pool and tbh I don't either - I'll do so down the road.

What is the right strategy to do automatic restores to the secondary from our nightly delta backups on a QNAP NAS?~~

edit: ok, I have found my answer, I should do streaming.

Another question, My XOA VM has the same IP address as my xcp hypervisor. How do I change it?
