Thanks, I'll try to get it compiled, and as a fallback I could make a stub if everything else fails. > > I'm using linux-2.6.26.8, uClibc-HEAD(linuxthreds, almost complete > > setup) and gcc 4.3.3. > > > > Also, is this kernel version supposed to work with this kvm? > > > > Yes. Actually only the headers are 2.6.26.8, the oldest vesion found in buildroot. (I wonder why are older ones being abandoned, since the new ones tend to get bigger and bigger.) The kernel will be 2.6.24 because it's smaller. I know this mismatch may not be good, but I have to get to a compromise. The kernel needs to be as small as possible (everything should fit in a 4MB BIOS flash), and also to support both this version of KVM and OpenVZ at the same time. Older KVM versions have terrible buildsystem issues and I gave up trying to get them compile in buildroot. I think OpenVZ could work on 2.6.26 too, but I haven't tried yet. Could this be a real problem at runtime? Thanks, Cristi. -- Ing. Cristi Măgherușan, System/Network Engineer Technical University of Cluj-Napoca, Romania http://cc.utcluj.ro +40264 401247
