Actually, I only get the error when using cache='none' -- writethrough and writeback both work, and default works also but the cache parameter is gone from the driver element if I do a dumpxml. i also forgot to include versions: cloud1:~# qemu --version QEMU PC emulator version 0.12.5 (Debian 0.12.5+dfsg-3), Copyright (c) 2003-2008 Fabrice Bellard cloud1:~# virsh --version 0.8.6 --Igor On Sat, Jan 22, 2011 at 12:49:55AM -0600, Igor Serebryany wrote:
hi,
i tried to add a 'cache' argument to the 'driver' element in my domainxml for qemu/kvm. i tried adding cache="none" as well as "writethrough" and "writeback", but every time i get these errors:
libvirtError: internal error process exited while connecting to monitor: char device redirected to /dev/pts/1 qemu: could not open disk image /vms/test.img: Invalid argument
the full driver line looks like this: <driver name="qemu" type="raw" cache="none"/>
the same domainxml works just fine without the cache parameter. does anyone know what i'm doing wrong? is there some other way to set the default cache policy on qemu/kvm? i didn't see anything in the config file...
