I got the Arch Linux (march build) iso file through bittorrent lately.

I tried to run it in VM, but it only gets up to the main screen (The screen where you select what you want to do) shown below:

But when I select first option, it shows a black screen which goes nowhere. The Hardware Information option seems to work, but it's out of my intellectual capacity so I ignored it.

I then tried qemu with a simple qemu-system-x86_64 ./location to file command. It shows a slightly different image:

On selecting x64-86 I get errors:

I am a Ubuntu user, so I don't get anything of this, but the first error seems to be:

failed to access perctr msr(msr coo1ooo4 is 0)

    I'm not sure about the perfctr message so I won't say anything about it but the message after that ("XZ-compressed data is corrupt) is worrysome. Did you verify your ISO file with any of the checksums at archlinux.org/download ? The easiest way to do that would be md5sum path-to-the-file or sha1sum path-.... – Wieland Jul 6 '14 at 9:48
  • @Wieland I would surely do, but the problem is I have old ISO from march. How do I get sha1sum/md5sum for it? website only provides latest ISO's sha1sum/md5sum. If you have old ISO sha1sum/md5sum, please provide it. – Registered User Jul 6 '14 at 13:23
  • archlinux.org/releng/releases/2014.03.01 has checksums for the old isos. – Wieland Jul 6 '14 at 14:06

    @Wieland You were right. The ISO was tampered one. the checksums did not match. But how did I got wrong ISo even after getting it from official site's official Torrent? Should I use direct link instead? – Registered User Jul 7 '14 at 14:27
  • I don't know how you got a corrupt ISO. Did you download a newer one and does it work? – Wieland Jul 8 '14 at 13:02

I get this message (failed to access perctr msr) on boot with a functioning Arch guest in Virtualbox. This issue has been discussed on the Arch forum (link below) and apparently is related to a cpu feature that does not exist on the system giving the error message, but the feature is unimportant, thus the message may be ignored.

Probably something unrelated, maybe booting without "quiet" would reveal what exactly is happening before it hangs.

Thank you! After booting without 'quiet', I found where the problem is.
