The environment on my side may be different from the link. My VM1 can be used normally after it is started on host2, but there is still information left on host1 that is not cleaned up.

Only the interface and background can still get the information of vm1 on host1, but the vm2 has been successfully started on host2, with the HA function.

I would like to ask a question, whether the UUID of the virtual machine is stored in the database or where is it maintained? Is it not successfully deleted after using the HA function?

I checked the vm1, he is keep up state, and can be used, but on host1 has after shutdown is a suspended vm1, this cannot be used, this is the problem now. 

In host1, you can get the information of vm1 using the "vdsm-client Host getVMList", but you can't get the vm1 information using the "virsh list".

Maybe a side effect of https://bugzilla.redhat.com/show_bug.cgi?id=1505399 

Arik?

Hi:

The current environment is as follows:

Ovirt-engine version 4.2.0 is the source code compilation and installation. Add two hosts, host1 and host2, respectively. At host1, a virtual machine is created on vm1, and a vm2 is created on host2 and HA is configured.

Operation steps:

Use the shutdown -r command on host1. Vm1 successfully migrated to host2.

When host1 is restarted, the following situation occurs:

The state of the vm2 will be shown in two images, switching from up and pause.

When I perform the "vdsm-client Host getVMList" in host1, I will get the information of vm1. When I execute the "vdsm-client Host getVMList" in host2, I will get the information of vm1 and vm2.

When I do "virsh list" in host1, there is no virtual machine information. When I execute "virsh list" at host2, I will get information of vm1 and vm2.

How to solve this problem?

Is it the case that vm1 did not remove the information on host1 during the migration, or any other reason?

Did you also check if your vms always remained up?

In 4.2 we have libvirt-guests service on the hosts which tries to properly shutdown the running VMs on host shutdown.

 

Thank you.
