Hi everyone, I'm working qemu with vhost target (e.g. spdk), and I attempt to migrate VM with 2 local storages. One local storage is a regular file, e.g. /tmp/c74.qcow2, and the other is a malloc bdev that spdk created. This malloc bdev will exported to VM via vhost-user-blk. When I execute follow

[Qemu-devel] QEMU migration cancellation

2017-10-11 Thread Jag Raman
Hi, I'd like to check about the behavior of a QEMU instance when live migration is cancelled. If the migration of a guest OS from source QEMU instance to destination instance is cancelled, the destination instance exits with a failure code. Could you please explain why this design decision was t

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 su

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 q
