Hi! I have a system with 2 processors and 4 cores each, which sums up to 8 processors in total. I installed the system with Gentoo.2008 and KVM-84.
Linux asok04 2.6.27-gentoo-r8 #1 SMP Tue Mar 3 11:34:26 CET 2009 x86_64 Intel(R) Xeon(R) CPU X5355 @ 2.66GHz GenuineIntel GNU/Linux
Everything is running fine as long as I do not change the default setting of CONFIG_NR_CPUS=4 in the kernel config: asok04 ~ # lsmod Module Size Used by kvm_intel 39176 1 kvm 137072 1 kvm_intel scsi_wait_scan 1664 0 asok04 ~ # All KVM modules are loaded and I'm perfectly able to start and use virtual guests. However, if I increase CONFIG_NR_CPUS to any number higher than 4, the additional processors of my system are listed in /proc/cpuinfo, but this is the output of lsmod: asok04 ~ # lsmod Module Size Used by kvm 137072 283728377 scsi_wait_scan 1664 0 asok04 ~ # Manually loading the kvm_intel module fails with an "Cannot allocate memory" error. Also starting VMs fails since he is unable to find /dev/kvm. This mail seems to be somehow related to the bug report of Justin Keogh from 30th Dec 2008. He was able to fix his problem by simply setting CONFIG_KVM=m, but I'm already using modules, so his workaround can't be applied here.
