Hi, My Dom0 is 32bit Linux. I am wondering if it is possible to install 64bit HVM (Linux) as guest? Thanks, Jun _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

You need new enough Xen for this.. >= 3.1 iirc. -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

But from Dom0, how to compile Xen to 64bit?

(My Dom0 now is 32bit)64-bit chroot, or simply a re-targetable tool chain. I think gcc+binutils can target x8664 fine with the -m64 switch, even if their host arch is i386. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
