I'm installing Centos 5.5 on a new Dell R301 server. I wanted to run Xen and have the full virtualization possibilities (this is our development support server, so it runs a few real services and is available for playing with things; putting the "playing with things" functions into virtual servers would protect the "few real services", and make it easier to clean up afterwards). I have enabled virtualization support in the BIOS. /proc/cpuinfo says I have model name : Intel(R) Xeon(R) CPU X3450 @ 2.67GHz and flags : fpu tsc msr pae cx8 apic mtrr cmov pat clflush acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc ida pni est ssse3 cx16 sse4_1 sse4_2 popcnt lahf_lm The "vmx" flag doesn't appear to be set. (I'm working from <http://www.centos.org/docs/5/html/Virtualization-en-US/ch-op-sys-support.html>, by the way; I note that document is from 2007 or maybe even 2006, so perhaps some things aren't fully up-to-date.) So, does that mean my Xeon-based server doesn't have hardware virtualization assistance? -- David Dyer-Bennet, dd-b at dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info

Many systems ship with them disabled.
