Revision as of 02:59, 26 November 2013

Merge KVM article into QEMU

Because the QEMU-KVM fork of QEMU has been deprecated/obsoleted as of QEMU 1.3 [1] (about 9 months ago as of this writing [2]) 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.

Does anyone disagree?
-- Jstjohn (talk) 16:29, 16 September 2013 (UTC)

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.
-- Kynikos (talk) 01:06, 18 September 2013 (UTC)
The problems of KVM#Tips_and_tricks should be solved along the way, especially KVM#Live_snapshots which belongs to libvirt and not to QEMU. It should also be clearly stated which features are KVM-specific to avoid confusion.
-- Lahwaacz (talk) 10:44, 22 September 2013 (UTC)
I just merged KVM#Live_snapshots into libvirt.

Works with "AMD FX(tm)-8350 Eight-Core Processor" using 2013.11.01 64-bit

Using Arch Linux release 2013.11.01 in 64-bit 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 the Gentoo minimal ISO 20131010 in 64-bit 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 live CD boot up... I see this error message... which I think is normal...
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" for 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
