Hi, before doing this migration 1. Did you test a migration to non-rbd storage succesfully without this bad behavior after migration? 2. Did you install and run another vm on your rbd storage? Does this vm perform normally? Regards Steffen >>> Nikola Ciprich schrieb am Mittwoch, 13. Januar

Hi Nikola, are the virtualisation hosts based on equal hardware (especially cpu)? What are the qemu parameters for the disks? Do you use virtio drivers and caching options? My default is -drive format=rbd,file=rbd:kvm/awv66_c:id=kvm,media=disk,if=virtio,discard=on,cache=writethrough where kv

Hi, the vnc option can handle the port dynamicaly with -vnc :0,to=x where the next open port is used from 5900 on to 5900+x. You then can get the used port via monitor command info vnc or assign it to a variable VNC_PORT=$(echo "info vnc" | socat - UNIX-CONNECT:${FILE_MONITOR} | grep address

2018-03-23 Thread Steffen Weißgerber
Hi, maybe you want this in general, not only for qemu. Then use Gentoo Linux. There buliding from source is the standard way to install applications. On a running system a 'emerge qemu' does the job. And so called use flags control the features you want to compiled in. ===
