Documentation is available on Xen Project 4.6 Man Pages
The default installation prefix has been changed to /usr/local. Previously the default installation prefix was /usr To restore the previous behaviour, specify --prefix=/usr when running ./configure, e.g.:
$ ./configure --prefix=/usr
If you choose to accept the new default then be sure to cleanup any residual bits of the old installation in the old prefix, especially libraries and tools which you might pick up by mistake.
Due to this change it may also now be necessary to run /sbin/ldconfig as root after installing Xen.
Note also that Xen now requires gcc v4.1 or greater.
Build with Raisin
Besides conventional "./configure; make" routine, you can also build with Raisin.
git clone git://xenbits.xen.org/raisin.git cd raisin cp configs/config-4.6 config ./raise -y build
While we did the utmost to get a release out, there are certain fixes which were not complete on time. As such please reference this section if you are running into trouble.
- Block script with QEMU is broken.
- Can't build debug version of toolstack. This was discovered shortly after we tagged RELEASE-4.6.0, use this patch to fix it.
