At least installer required some option to omit host OS check, it's in the `runInstaller -help' output somewhere, and there was something about gcc version (it needs gcc-3.4 at max if memory serves me right, or even 2.95).

kvm-kmod-88 compilation fails on RHEL 5.4
Good afternoon,
I have some issues to make KVM working on Red Hat Enterprise Linux 5.4
32 bit edition. I have downloaded the kernel-2.6.18-157.el5.src.rpm
from Red Hat Network in order to compile kvm-kmod-88 on it. But each
time I try, I've got an error:

I tryed with kvm-kmod-85 too, and even kvm-88 (but i think it's not
adviced because RHEL kernels are too old).
KVM modules successfully loaded on the kernel 2.6.18-157.el5-i686 with
kvm-kmod package found on lfarkas.org centos5 repository, but it
doesn't with PAE kernels, and that's what i need finally.

Re: kvm live migration reliable?
Kent Tong wrote: Hi, I was wondering the kvm live migration function is reliable? I read that if the TSC is not monotonically increasing, then the guest will hang. How to prevent this? KVM transfers the tsc as part of the CPU state so it will continue to increase monotonically. However, if you're migrating between two CPUs of different frequency, the result will be that the TSC frequency will change. This could have negative effects depends on how much the guest relies on the TSC. The worst case would be if your guest was Linux and was using TSC as a time source. You would likely see severe time drift. A PV clock source (like KVM_CLOCK) helps this quite a bit.

slow responsiveness of kvm guests
Hi, i have three guests running via qemu-kvm. All three are webservers using apache2/django and mysql. System load is very low on all guests and the host, too. Guest 1 reaction times (web server, ssh) are fine as long as no other guest is getting busy. When i ssh to guest 2 it takes 5-15 seconds until i get a login. When i run top or htop on one of the guests the other guests don't react for 5 seconds (webservers or typing in ssh shell). My colleagues already try to convince me to use xen instead... already - disabled apm and acpi in the guests - turned Hyperthreading off - tried different i/o schedulers: cfq vs. deadline. Result is the same. - nailed down guest process via taskset to separate cpu cores host is OpenSuSe 11.1 x86_64 kvm-78-6.5.1 2xXeon 5550 Nehalem (Quadcores, Speedstep-enabled) 48 GB RAM 1 GB Ethernet as tap interface all three guests are Debian 5.0 x86_64 two virtual cpus 4GB RAM (hugepage-backed) started via qemu-kvm -hda xyz.qcow2 -daemonize -net nic,model=virtio -net tap -k de -m 3584 -smp 2 -mem-path /hugepages -vnc :2 Any ideas what goes wrong here?
