Hi all, I'm trying to switch from xen to kvm. I already successfully installed and tested kvm-84 on a CentOS 5.3 but before put it in production I'd like some advices from you: 1) I'm trying to settle and use one version of kvm maybe backporting some patches when needed. What version do you suggest me to use in a production environment? 2) I'm pretty much confused about kvm-x and qemu-kvm, anyway I used kvm-84 with no problem and lately I'm testing qemu-kvm 0.10.5 with the kvm-84 kernel module. Is this combination (kvm-84 kernel module and qemu-kvm 0.10.5) right? Is there a better one? 3) What is the difference between qemu-kvm 0.10.5 (on the kvm sourceforge site) and qemu 0.10.5. Which one do you suggest me to use in a production environment? 4) I saw that the rpm packages for CentOS (provided by lfarkas.org) are based on qemu 0.10.4, is there a reason? is it a very stable release? I tried to contact Farkas but I had no reply yet. The last question might be split in a new thread: 5) I tried to use qcow2 images with migration (storing them on gfs) but the migration fails very frequently (mostly on heavy disk load). I think the problem is that the new qemu-kvm (the -incoming one) reads (or tries to read) the qcow2 headers before receiving the full ram memory image and during the transfer time the qcow2 file get modified by the old qemu-kvm (the dying one) which flushes the disk cache. Is anyone else trying to let qcow2 work with migration? I also heard that RHEL 5.4 will be featuring kvm, if the kvm redhat team is already working on these same issues I'd be definitely pleased to contribute with my current testing experiences. Feel free to contact me.
