[ANNOUNCE] kvm-29 release

[ANNOUNCE] kvm-29 release

[Avi Kivity]

Well, I really wanted to have guest smp in the release, but alas, it was 
not to be.  It still doesn't like starting X, for example.

Note: on i386 the qemu binary is now named qemu-system-x86_64.  This is 
to allow migration from 32-bit hosts to 64-bit hosts, and to allow 
32-bit userspace on a 64-bit host to launch a 64-bit guest.

Changes from kvm-28:
- live migration from 32-bit hosts to 64-bit hosts (Uri Lublin)
- monotonic timestamp counter on Intel
- more real mode support (Nitin A Kamble)
- infrastructure for in-kernel PIC and APIC (Gregory Haskins, Eddie Dong)
- fix read-modify-write to mmio (fixes F7 installer) (Luca Tettamanti)
- fix rebooting a long-running guest
- reliably detect if svm was disabled by bios (Joerg Roedel)
- suspend/resumes fixes (will not work with older kernels)
- fix nx confusion with large pages and real mode
- remove dependency on libuuid
- fix registers access in monitor/gdbstub (Anthony Liguori)
- minor fixes and cleanups (various)

Notes:
    If you use the modules from kvm-29, you can use any version of Linux
from 2.6.9 upwards.
    If you use the modules from Linux 2.6.20, you need to use kvm-12.
    If you use the modules from Linux 2.6.21, you need to use kvm-17.
    Modules from Linux 2.6.22 and up will work with any kvm version from 
kvm-22.  Some features may only be available in newer releases.

Framebuffer error

[Víctor Abeytua García]

Hello,
	I know this is not probably the place, but as I haven't found a
kvm-users list and probably some of you have encountered the same problem I feel
it's the best place to post my problem.  I have a macbook pro running Feisty
with a Radeon Mobility X1600 and VMX cpu support and I was quite interested in
trying kvm. I followed the steps of any of the online manuals, but I didn't get
far. As soon as I tried to install Windows XP:

	kvm -no-acpi -m 384 -cdrom /dev/cdrom -boot d windows.img

	I obtained  the following output:
	
       ---------------------- DirectFB v0.9.25 ---------------------
             (c) 2000-2002  convergence integrated media GmbH  
             (c) 2002-2004  convergence GmbH                   
        -----------------------------------------------------------

(*) DirectFB/Core: Single Application Core. (2006-12-20 21:25) 
(*) Direct/Memcpy: Using MMX optimized memcpy()
(!) Direct/Util: opening '/dev/fb0' and '/dev/fb/0' failed
    --> No such file or directory
(!) DirectFB/FBDev: Error opening framebuffer device!
(!) DirectFB/FBDev: Use 'fbdev' option or set FRAMEBUFFER environment variable.
(!) DirectFB/Core: Could not initialize 'system' core!
    --> Initialization error!
Could not initialize SDL - exiting
	
	I checked and couldn't find any framebuffer device in my computer. After
googling a lot, creating those devices manually, trying to boot with both the
propietary and open source driver, loading the radeonfb module I haven't been
able to avoid this problem. Could someone in the list enlighten me?

	Best regards,
	Víctor

This is strange.  You're running in X, right?  Is $DISPLAY set 
correctly?  Maybe some other environment variable is telling SDL to use 
a framebuffer instead of X.

Thanks a lot,
	I was looking at the wrong place. I was trying to launch the
installation as root after sudoing. And as root I didn't have the DISPLAY
variable. Now the installation is proceeding smoothly.

	Best regards,
	Víctor

Re: Framebuffer error

[Benjamin Budts]

I had the same problem, I missed couple of SDL packages...

here is my package list under debian :

 ii  libsdl1.2-dev                     
1.2.11-8                            Simple DirectMedia Layer development 
files
ii  libsdl1.2debian                   
1.2.11-8                            Simple DirectMedia Layer
ii  libsdl1.2debian-alsa              
1.2.11-8                            Simple DirectMedia Layer (with X11 
and ALSA

also check the following file :
/sys/class/misc/kvm/dev

I had to create a file manually using mknod...

mknod /dev/kvm c  (low and high number of the file above

hope this helps you out
