I just got the fix for it today. It's not in any tree yet, but since you're using git, I'll assume you're confortable with applying a patch in your tree ;-) You can download it from http://glommer.net/0003-restart-search-at-beggining-of-vmalloc-address.patch ---------------------------------------------------------------------- Comment By: walt (w41ter) Date: 2008-11-07 21:07 Message: FWIW this seems to be a 32-bit-only problem for me. I track Linus.git and kvm-userspace.git in 32-bit and 64-bit linux installations on one machine, and the 64-bit kvm works perfectly. Only the 32-bit kvm has this error. Can I work around the problem with vmalloc=<size>? If yes, where do I use that vmalloc flag? Thanks. ---------------------------------------------------------------------- Comment By: Torsten Wohlfarth (towo2099) Date: 2008-11-03 21:13 Message: Yeah, there are many messages about vmalloc: http://rafb.net/p/4RvqBX81.html ---------------------------------------------------------------------- Comment By: Glauber de Oliveira Costa (glommer) Date: 2008-11-03 21:08 Message: check your dmesg in the host. If there's any message about vmalloc failing, so this is a known issue. I have a band aid patch that helps it, but we're still not sure what the proper fix is. I'm working on it right now. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2219447&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
