我们新买了一个服务器Xen3.0×2（64），6G内存，73G×6，想装Linux，Gentoo的Amd64位版能够运行吗？还是用X86版

建议用centos或redhat的x86－64版

KDE

最好不要跨平台运行。

用centos4.2在P D上跑着。gentoo不知道

呵呵，看来还得用Rh。有一些郁闷。

[code:1]The AMD line of 64-bit extended processors were released well ahead of Intel's offering. Therefore, for historical reasons the arch keyword for all x86-64 compatible architectures is amd64.[/code:1][code:1]What CFLAGS should I use for AMD64/EM64T?

You should use simple CFLAGS to avoid future problems with your system. For example, you should use CFLAGS="-march=k8 -O2 -pipe" for Athlon64 or Opteron and CFLAGS="-march=nocona -O2 -pipe" for a EM64T processor. If you plan to use a 32-bit chroot, you should use CFLAGS="-march=athlon-xp -O2 -pipe -msse2" for a AMD64 processor; for a EM64T, you should use CFLAGS="-march=pentium4 -O2 -pipe" inside the chroot.

CFLAGS="-march=nocona -O2 -pipe"
