| |
Hi,
I'm using KVM and the qemu kvm modified to run a windows guest. I'm allocating 900 MB to the guest. Seems that when I terminate a qemu process, the memory that was allocated to qemu is not freed:
Mem: 2058140 1739156 318984 0 226944 425140 -/+ buffers/cache: 1087072 971068 Swap: 0 0 0
So I'm using 1GB of ram even though I've terminated qemu. If I attempt to start qemu again, the machine locks up. No message in the logs.
Command to start qemu: /usr/local/kvm/bin/qemu-system-x86_64 b.data -no-acpi -m 900 -net nic -net user -hdb temp.raw -usbdevice tablet
uname -a Linux ops-desktop 2.6.25-rc5-git5 #1 SMP PREEMPT Sat Mar 15 14:47:25 EET 2008 x86_64 GNU/Linux
Not sure whether this is a problem on the kernel side. I don't pretend to understand linux memory management. But it wasn't occurring with older kernels. I'll attempt to bisect.
