Re: [ovirt-users] Mirgration issues

Wednesday, 1 March 2017

to use virsh you can set password:

 saslpasswd2 -a libvirt foo (foo is some username)

then use virsh with that username as usual

 Hi All,

 so sorry for not seeing this. I used vdsCLient just because I didn’t know
 how to get virsh working. (It asked for user/password) Now that I managed
 to get this working things look different

 [root@ovirt-node02 ~]# vdsClient -s localhost list table

 e051b38c-fd63-40f0-8d64-26c12ff7b880  41294  HostedEngine
 Up                   172.16.1.9

 [root@ovirt-node02 ~]# virsh -r list --all

  Id    Name                           State

 ----------------------------------------------------

 1     HostedEngine                   running

 -     data_p                               shut off

 How could this vm persist over reboots and reinstalls? And how would I
 remove this ?

 Just random thought: try to reinstall the "bad" host:)

 I’ve setup the cluster with 4.05 and the SSL error came up later I think.
 I couldn’t find anything to solve this so far. I remember reading a bug
 report about it and that it’s not fixed yet.

 I have rebooted all hosts and made sure that selinux is enforcing. I also

 I can’t migrate it to host 2 even after a clean reboot with nothing running

 Hi,

 I even tried that after restarting host 2 and at this point I’m sure there
 were no VMs running.

 it’s may be a bit different if you look at that via libvirt

 does it really not show anything else even when you do

 "virsh -r list --all” ?

 Martin, what does “HA” filer do?

 Can you check on host 2 if you have any VM already running there ?

 You can use :virsh list

 Hi All,

 I’m having issues with migrating a VM. I have a 3 Host cluster and the VM
 is able to migrate between host 1 and 3, but not to host 2.  I don’t know
 why and I tried figuring this out with the log files and had no luck. All
 other VMs migrate to the host 2 without any issues.

 If you have some advice for me that would help a lot.

 Thank you,
