This is just the size of the vram allocated by qemu, I saw this in the code. > In my tests with cirrus/stdvga, in a Linux guest lspci always report 32M and > Xorg.0.log report "VideoRAM: 4096 kByte".

For the 4MB instead of 8 reported by Xorg, I don't know. There is probably a reason why Cirrus will report 4 instead of 8. > Is there a better way to check videoram and videoram usage in a Linux or > Windows guest? I don't think so. -- Anthony PERARD _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
