So a 9.1 userland with a 10 kernel will work. However, running a newer userland on an older kernel is not guaranteed to work. So running a 10 userland with a 9.1 kernel will most likely not work. However, since you guys are doing very cutting edge stuff with 10-CURRENT, it is better that you do not waste time with 9.1. I recommend you start with a 10.0 CURRENT snapshot ISO and go from there. I am going through a similar setup exercise with a Google Summer of Code student where he needs to have a latest CURRENT system running in a VM. I wrote this blog post: http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gsoc-work/ for the steps how to do it. You can follow those steps to get bootstrapped with a working environment if it helps you out.

I am going through a similar setup issue with someone who has signed up for Google Summer of Code, and I need him to use close to the latest 10.0-CURRENT and have a usable system. I wrote this blog post for the student: http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gsoc-work/ You may wish to follow those steps to configure your system to download packages from one of the 3rd party pkg mirrors, and then use the "pkg" command to install gmake and whatever other packages you need. Outback Dingo has mentioned using "pkg" command for installing packages in 10-CURRENT, and that is what I am instructing my GSoC to do.

Did you install the ports tree during the installation? If so I've always successfully installed git using: # whereis git # cd # make install Maybe the ISO you picked as a broken ports snapshot? ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"

Anything else I should > try testing? Thanks for the test, this is what I expected. I'm a little bit out of ideas since I'm not able to reproduce this on upstream Xen 4.2. Without knowing what's happening inside the hypervisor it's hard to tell what's wrong. It would be interesting to try if the same happens with a Linux PVHVM (not PV) running on the same instance type. ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
Re: FreeBSD PVHVM call for testing
Hi, I've just successfully run FreeBSD 9.1 based guest with 'pvhvm_v8' based kernel under Xen 4.2.2. So I couldn't confirm any issue with the kernel both on Xen 3.4.4 and 4.2.2. Nice Job.
