Hi I have been trying to do some testing of a large number of guests (72) on a big multi-node IBM box (8 sockets, 32 cores, 128GB) and I am having various issues with the guests. I can get the guests to boot, but then I start to have problems. Some guests appear to stall doing I/O and some become unresponsive and spin their single vcpu at 100%.
Each guest is configured with 1 vcpu and 1000MB of memory. The single virtual disk is backed by a LVM volume. Both the guest and host are running custom kernels. I have tried kvm-67, kvm-64, and kvm-62 (not functional at all). I have cloned both the kvm and kvm-userspace repositories and am building the tagged changesets from each. Here are a few of the various things I have tried: virtio and emulated devices for the nic and disk; mixed virtio and emulated devices; kvm-clock and clock=jiffies. Any help in pinpointing the problem would be appreciated. Thanks. -- Karl Rister IBM Linux Performance Team [EMAIL PROTECTED] (512) 838-1553 (t/l 678) ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
