Dear All,
I'm trying to install a Debian Wheezy KVM guest on a CentOS 6.4 Host. The only resolutions supported are 1024x768 or 800x600.
I increased the video RAM to 500 MB, but the guest still says:
[ 10.321] (II) CIRRUS(0): Not using default mode "1920x1200" (insufficient memory for mode)
Only 32 MB are recognized:
00:02.0 VGA compatible controller: Cirrus Logic GD 5446 (prog-if 00 [VGA controller]) Subsystem: Red Hat, Inc Device 1100 Physical Slot: 2 Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Region 0: Memory at f0000000 (32-bit, prefetchable) [size=32M] Region 1: Memory at f2000000 (32-bit, non-prefetchable) [size=4K] Expansion ROM at f2010000 [disabled] [size=64K]
How can I increase the resolution? Are any guest modifications necessary?

For better video performance switch from VNC to Spice display and QXL video card.
