[20:42 xenserver ~]# reboot

Thank you again! This did the magic trick.

Hi,

I reinstalled my XCP-ng server. Before that I exported all vm's to a network storage (via powershell script).

After reinstalling the new server (booting from SSD and created a new virtual disk on my raid controller for local storage replacing the previous 2 virtual disks) I installed the XOA appliance with the quick install option from the server webpage.

When I choose "Import - VM" I can drag and drop the xva of my choise and start the import.
After the import is finished I am prsented with the overview of a new VM in XOA.
When I try to start the VM or for example want to change the network settings, I get an error "no such VM 682c77dd-2448-7447-4a8e-783748408516".

When I look at Home - VM the VM is also not listed there.
When I look at home - Storage - MySR - Disks, the disk is listed and showing to be attached to a VM (that does not exist).

Is this a bug, am I doing something wrong, or are my expectations of having a working VM after importing wrong?

Workaround I found for now:
the imported VM is showing up under templates. So I create a new VM based on the template. This VM is working as expected.
Only issue is I have two disks then (taking twice the storage space?)

@moussa854
how have you configured the network for your vm?

since you already have pfsense wan with a private ip I would think you connect the wan side of the vm to the same wan network (also getting an ip handed out by your providers router?)
lan side you de not want on the same lan network as pfsense, so a separate network connected to your wifi points?

@moussa854

as I look at it this can all be done with the user interface of xcp-ng (xoa or xcp-ng center).
first create a network connected to a physical nic and use that as wan for openwrt
then create en internal network (or use another nic) and use that as lan for openwrt.

create a new vm for openwrt (import the virtual disk of openwrt) connected both networks created above.

ps what is the use of openwrt when you already have pfsense?
both are basically routers

@stormi @r1 thank you! I do not have the equipment to test with ch8.1 but this is solved already I see. great catch

Did some googeling and testing, but could not get the ISO repository to connect.
Finally simply deleted the repository and created a new one to the same samba share. That worked at once.

Think I might have created the issue myself bij not having ejected one "cd" from one of the vm's. Not sure is this was the cause, but will update my own documentation to eject all cd's first

• Another thing I noticed is my VM's I set to autostart at boot do not autostart anymore at all.

I already tried removing and setting the autostart option again for those vm's in XO, but after a reboot they still do not autostart

Ok, new issue after the update:
After the reboot of the server none of the VM's were started (including the VM with XO from the sources). I checked this in the status screen with a display connected to the server.

I downloaded the latest daily version of xcp-ng center. Was able to connect to the server but no vm's were started as suspected.

There I saw an error for my ISO repository that resides on my NAS (Samba). Trying to solve it from xcp-ng center did not work (SM has thrown thrown a generic python exception).

I was able to start the XO vm and from there when trying to reconnect the ISO repository I got this error in the log:
SR_HAS_NO_PBDS(OpaqueRef:d259a8f1-6bbe-46bb-b135-447bb352e888)

When trying to reconnect from the console:

I checked the /etc/ym.repos.d and there were repositories for CentOS-Base, -Debuginfo, -Sources, dell-system-update, epel and epel-testing. Only the dell repo was enabled, none of them contained references to xcp-ng

the other repo was like expected the xcp-ng.repo
This contained the reference to 8.0, not 8.1

I was able to make it work by again doing the copy command for the 8.1 repo I initially got with the wget from /root.
I checked and this time it did correctly replace the 8.0 repo to 8.1

I do not know why it did not do so before. There is no indication in the output the cp command did not do its' thing the first time.

Anyway, thanks for helping me and pointing in the right direction. Just started the update to 8.1 now
