I've uploaded the logs here: https://docs.google.com/open?id=0B78o7gMWkuFeY2FkNjllNjgtNDQyZC00NDU5LWFjODctNzMzNzU3NjNjODkz 'Xorg.0.log.outside' is the result of running KVM outside the chroot, which is fast as normal. 'Xorg.0.log.inside' is the result of running KVM inside the chroot, which is slow. 'diff' is the diff obtained by first removing the timestamps from the log files. I think you're right re: linear framebuffer Avi. The last part of the diff shows (< fast > slow) 1377c2113 < (II) VESA(0): VESA VBE Total Mem: 8192 kB --- > (II) VESA(0): VESA VBE Total Mem: 16384 kB 1383,1385c2119,2123 < (II) VESA(0): virtual address = 0x75f11000, < physical address = 0xe0000000, size = 8388608 < (II) VESA(0): Setting up VESA Mode 0x145 (1280x1024) --- > (II) VESA(0): virtual address = (nil), <========== HERE > physical address = 0xe0000000, size = 16777216 > (II) VESA(0): virtual address = 0x76e6a000, > physical address = 0xa0000, size = 65536 > (II) VESA(0): Setting up VESA Mode 0x186 (1680x1050) 1409c2147 FWIW: (outside-OK) $ qemu-system-x86_64 -version QEMU emulator version 0.15.0 (qemu-kvm-0.15.0) (inside-slow) $ qemu-system-x86_64 -version QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5) However, running outside the chroot was also OK with 0.12.3. What could be causing this?
