If I understand you correctly, you are ensureing the kernel version of the host is greater than the guest - am I correct? I can't see the point in worrying about that at all. The host can be a completely different operating system to the guest. I run all my virtual machine (Linux and Windows) with a host that is Solaris. 77 >Is 1G memory enough to build Sage?

I've seen figures like 2.5 GB being needed to build the documentation. It must depend to a certain exent on exactly what else is running on the system. If you have very limited RAM, you will probably want to turn off anything not absoluety essentail - sendmail etc. > I have an 8G machine and would like to put 6 virtual guests on there: > 12.04.1 32bit and 64bit, 12.10 32bit and 64bit, 13.04 (development) 32bit > and 64bit; and to keep 2G to do PPA building on the host. I think you will fail with that. Each guest needs a bit of overhead. I don't know how much that will be, but I would be surprised if it < 80 MB -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
