here some news for kvm forum 2015 :) http://www.linux-kvm.org/images/b/b3/02x-09-Cedar-Liang_Li-KVMLiveMigrationOptimization.pdf for xbzrle, I think we could enable it by default, as it's has been optimized since this commit: http://git.qemu.org/?p=qemu.git;a=commit;h=27af7d6ea5015e5ef1f7985eab94a8a218267a2b for compression, slides said that for 10GBE, it's slower with compression. also for compression, we can configure number of threads and compression level http://git.qemu.org/?p=qemu.git;a=blob;f=docs/multi-thread-compression.txt (BTW, they are a lot of interesting doc for different topic from kvm forum 2015, http://www.linux-kvm.org/page/KVM_Forum_2015) ----- Mail original ----- De: "dietmar" <diet...@proxmox.com> À: "aderumier" <aderum...@odiso.com>, "pve-devel" <pve-devel@pve.proxmox.com> Envoyé: Mercredi 23 Septembre 2015 16:50:36 Objet: Re: [pve-devel] adding live migration options ?

If we add additional options, there should be a good reason. For example, why do you want to disable compression or xbzrle? Any benchmarks? _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
