Install FreeBSD paravirtualized DomU according to the HOWTO at: http://forums.freebsd.org/showthread.php?t=10268 2. The only difference from the original HOWTO is guest disk based on real Linux LVM volume instead of file image. 3. Xen and Dom0 details Linux xen0.vps 2.6.18-164.15.1.el5xen #1 SMP Wed Mar 17 12:04:23 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux CentOS release 5.4 (Final) Xen version: 3.4.2 4. Log into FreeBSd DomU via ssh and run 'sysinstall' to install ports collection. 5. Enter /usr/ports/lang/ghc and run 'make' 6. The last STDOUT message is the following 'configure' string: -- checking whether mlock is broken... -- 7. Check FreeBSD main console output >Fix: >Release-Note: >Audit-Trail: >Unformatted:
