Merge KVM article into QEMU
Because the QEMU-KVM fork of QEMU has been deprecated/obsoleted as of QEMU 1.3  (about 9 months ago as of this writing ) and QEMU is now on version 1.6, we should strongly consider merging the KVM article into the main article for QEMU. A separate article for the KVM fork made sense historically, but now that the fork has been merged upstream, we should just keep everything on one page.
- Good idea, I don't think anybody can disagree, as the main section of this article, KVM#How_to_use_KVM, already just links to QEMU ^^
- If then somebody considers QEMU to have become too long, it should be discussed to split it in some other way.

kvm user group
/dev/kvm is granted via ACLs:
... SUBSYSTEM=="misc", KERNEL=="kvm", TAG+="uaccess" ...
so adding the user to
kvm group should be deprecated. There are many references to this all around the wiki.
works with "AMD FX(tm)-8350 Eight-Core Processor" using 2013.11.01 64bit
Using arch linux release 2013.11.01 in 64bit mode... it boots fine. Following the wikis... this is basically the parameters I used
$ /usr/bin/qemu-system-x86_64 -boot d -m 1024 -hda '/home/user/path/to/storage' -cdrom '/path/to/archlinux-2013.11.01-dual.iso' -net nic,vlanx=0 -net user,vlan=0 -localtime -k en-gb -smp 8 -enable-kvm -cpu host &
- I also booted gentoo minimal iso 20131010 in 64bit mode ( go to gentoo to find out more ) using the same parameter but different iso
$ /usr/bin/qemu-system-x86_64 -boot d -m 1024 -hda '/home/user/path/to/storage' -cdrom '/path/to/install-amd64-minimal-20131010.iso' -net nic,vlan=0 -net user,vlan=0 -localtime -k en-gb -smp 8 -enable-kvm -cpu host &
- During livecd boot up... I see the error message
Failed to access perfctr msr (MSR c0010001 is ffffffffffffffff)
- You also get errors about not being able to access hardware... obvious why :p ( unless I'm wrong )
- I haven't installed arch linux in the guest yet ( busy :p ) but will get some time to
- from what I can see the parameter "nested" is already set to "1" in the "kvm_amd" module when using the "systool" command before applying the "nested" parameter myself
- I found loading "kvm" or "kvm_amd" loads both
- you should say "grep svm /proc/cpuinfo" for AMD
- I have another AMD machine which has "AMD Phenom II x4 955" ( showing the "svm" cpu flag from "/proc/cpuinfo" file which too is using arch linux ( my server ) when I have time... will try it out there
- I do plan to move to Intel... better drivers... lets get cracking before I move to Intel
- I'm new to wiki code :p
