Hi, For Proxmox, we have made some patchs to split the savevm process, to be able to save the memory to an external volume. (and not the current volume). For rbd, we create a new rbd volume to store the memory. qemu patch is here : https://git.proxmox.com/?p=pve-qemu-kvm.git;a=blob;f=debian/patches/internal-snapshot-async.patch;h=c67a97ea497fe31ff449acb79e04dc1c53b25578;hb=HEAD ----- Mail original ----- De: "Wido den Hollander" <wido@xxxxxxxx> À: "Oliver Francke" <Oliver.Francke@xxxxxxxx> Cc: ceph-devel@xxxxxxxxxxxxxxx Envoyé: Vendredi 24 Mai 2013 17:08:35 Objet: Re: qemu-1.5.0 savevm error -95 while writing vm with ceph-rbd as storage-backend On 05/24/2013 09:46 AM, Oliver Francke wrote: > Hi, > > with a running VM I encounter this strange behaviour, former > qemu-versions don't show up such an error. > Perhaps this comes from the rbd-backend in qemu-1.5.0 in combination > with ceph-0.56.6?
