Unable to migrate VMs

Darkbeldin

@fred974 Yes from the VM host the basic CLI is something like

xe vm-migrate uuid=<VMuuid> host-uuid=<Hostuuid>

fred974

@darkbeldin

[15:37 srv-tri-xcptmp ~]# xe vm-migrate uuid=8be08afd-f7c9-f044-661e-631b41b110b7 host-uuid=9eebc91d-3277-4f13-948e-f964ecf548d2

Error: Host 9eebc91d-3277-4f13-948e-f964ecf548d2 not found

This is strange as the host is visible XO

From the host the VM is on, I can telnet the destination host

[15:47 srv-tri-xcptmp ~]# telnet 85.75.xxx.xx 443
Trying 85.75.xxx.xx...

@fred974 Are you trying to migrate to the same pool or to another pool?

@fred974 Are you trying to migrate to the same pool or to another pool?
I am migrating to another pool on another DC. I am using zerotier to link the hosts. But the issue also exist when exposing the destination host IP to the public.

fred974

When I add the hosting using its public IP, I have the same issue. It is added to XO, I can list the VM on the destination host. I cannot access its console tough. I tried via the official XOA and same error.

Darkbeldin

@fred974 Sorry not sure i understand, from which host to which host are you trying to migrate? are they on the same pool?

@fred974 Sorry not sure i understand, from which host to which host are you trying to migrate? are they on the same pool?

I am trying to migrate 1 VM located in datacentre 1 to another host located on another datacentre on a completely different pool. There is 2 pools of 2 individual host.

Currently I am using XOA official from the host the VM reside. I added the destination host to that XOA via its public IP and I can see it in XOA but cannot access the console of the remote host from XOA for some reason.

The error at command line is saying that it cannot find the remote host, even tough it exist in XOA. Was I suppose to run the following command from the XOA server and not the host?

xe vm-migrate uuid=<VMuuid> host-uuid=<Hostuuid>

Darkbeldin

@fred974 No in the case of a remote pool you have to use other parameters.

xe vm-migrate vm=<vmuuid> remote-master=<remote pool master IP> remote-username=root remote-password=<password> vif:<uuid of the migration VIF>

fred974

@darkbeldin Do I need to specify the remote storage uuid?

fred974

@fred974 here is the error from command line

Your connection is reset. Check XAPI logs on source and destination, also check you have enough memory and disk space in the dom0.

On source or destination?

olivierlambert

Check both, that won't hurt

dom0 memeory is good on the host sending the VM. On the receiving host, it is low but from what I can see in XAPI log on the sending host, it doesn't even make it as far as the receiving host.

Indeed that's weird, like if something was blocked. I would check your network/FW and so on.

fred974

@olivierlambert Is port 80 and 443 all that is needed correct

olivierlambert

Yes, but there's something problematic somewhere in your case.

Have you restart the toolstack on destination?

@olivierlambert said in Unable to migrate VMs:

Yes I have, also rebooted. I just installed XOA on the destination server and added the sender server to it. It does connect and I can see all the VM. This time I can also access both hosts console in XOA but it still fail to transfer

It's not a failure/problem of XO, but your hosts (as you can see the same issue persists despite using xe, XCP-ng Center or XO).

Have you checked the disk space? Also raise the memory in the dom0.
