Hi,
We are trying qemu migration.
Suppose VM1 is migrated from hostA to hostB.
After complete migration, VM1 starts on hostB. But VM1 on hostA
remains in suspended mode.
We want to identify all live VMs on hostA.
We are not able to identify live VMs. 'ps -eaf | grep qemu' command
gives all the qemu processes.
Do you have any idea of to find all live VMs on host?
Please help.

If the guest is configured with an HMP console (qemu ... -monitor stdio, for
instance) you can use the command 'info migrate' to check the
in-migrate/post-migrate status of the guests
If the guest is configured with a QMP console (qemu ... -qmp stdio, for
instance) you can use the 'query-migrate' command to get similar
information

I want to get information in terms of number of active qemu processes.
How can I track this information from host?
As you said, the commands 'info migrate' can be run in qemu console.
For this, I have to switch to qemu console.
How can I get the information whether the qemu processes are live or
suspended from host?
