Low video resolution

[igadoter]

Hi,

I am completely new to virtualization in SL. I am running SL 6.4, I created virtual machine, but I am unable
to set video memory larger than 9 MB, also the maximal video resolution for guest is 640x480, which is too
small. I need much higher resolutions.

Any hints ?

Hi,
i suppose the the KVM machine is Linux? if it is, then, id go some like this:

CODE

1. edit HW details of the VM ('show virtual hw details' icon) - change video card to 'vga' (from cirrus) 2. vi /etc/X11/xorg.conf.d/xorg.conf Section "Monitor" Identifier "Monitor1" HorizSync 31.5 - 90 VertRefresh 50.0 - 180.0 Option "PrefferedMode" "1280x1024_60.00" EndSection Section "Device" Identifier "Device1" Driver "vesa" EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 16 SubSection "Display" Depth 16 Modes "1280×1024" EndSubSection EndSection

cheers,

The guest is Plan 9 system, at this moment I am worried most about that supervisor sets maximal
amount of graphic memory to 9MB, I can't change this, It deos not matter what type of graphic card.

Hi,
sorry, this topic slipped off my radar 'a bit' (me being at vacation at the time) and i found it 'again' while having a bit of time and reading forums.

I know you read/post to our forums - could you share (if you will) how you solved the Plan 9 problem?

I find it interesting very much. I dont know Plan 9 - but after internet search it turns out to be a very interesting OS.
What are you using it for? Wiki says it's EOL since 2002 ..


Anyway as for the low res - yes, KVM is topped at 9MB per guest by default and it can't be changed in 'virt-manager'.

But you can change it from CLI (eg. from my laptop):

List domains:

CODE

virsh list --all Id    Name                           State ---------------------------------------------------- -     389DS-final                    shut off -     389DS-final-clone-bck          shut off -     389DS-final-clone-dirsrv1      shut off -     389DS-final-clone-dirsrv1-clone-bck shut off -     node1                          shut off -     node2                          shut off -     vm03-win764-dpdhl              shut off -     win7pc04                       shut off

Change domains (eg. my windows guest):
find the 'vram' setting and increase it from default to what you need

CODE

virsh edit win7pc04 <model type='vga' vram='18432' heads='1'/>

restart libvirt:

CODE

service libvirtd restart

Now you see it in virt-manager too.

cheers,
