Hi all,
I will want to try VMWare ESX to test new features but I do not have a
server that meets the ESX requeriments ... but is it possible to run ESX
under Xen (maybe a silly question)?
Thanks.

IOW, those systems would have to be Xen-aware to run under Xen, just like the linux kernel have to be modified.

I''ve always wondered how they got around the GPL. Anyway you could probably run Xen in an ESX VM but not the other way around. -- Some days it''s just not worth chewing through the restraints...

One thing you could do to start with is check the devices ESX supports (Xen emulates a PCnet device (or optionally an NE2000, I think) and a Cirrus VGA adaptor... if ESX doesn''t support these then you''ve already got problems!).

(that''s the "para" in > "paravirtualization")Oh yeah, I kinda assumed the original poster was running on VMX hardware - but if you''re not, you can''t run unmodified operating systems (like VMware ESX) at all, sorry. QEmu in non-accelerated mode will emulate a whole machine entirely in userspace, so that might be worth trying. Again, I''m not sure ESX will actually support the hardware QEmu provides but it might be worth a shot. It''s likely to be quite slow, though ;-) Cheers, Mark _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I have attempted to get VMWare ESX running under Qemu/Xen/KQEMU without success. If Qemu supported SCSI hardware it would present a working option...but it does not and the VM''s are based on SCSI hard drives. The cheapest hardware that it will run on is somthing like a compaq proliant 1600. Which is what I currently have for VMWare ESX...I have 3 VM''s running (all linux) Windows is more of a memory hog and this error of computer only supported 1 gig of memory which isnt enough to get but a single windows VM running. You might want to look at PIV servers that supported 3-4 gig of ram but they are more expensive for sure. You also need a storage area network for VM migration with VMotion product since it does not support ISCSI in its current incarnation. They say ISCSI support will be available in the next ESX version but ISCSI would require integration of a whole TCP/IP stack into VMKernel which is a stability headache at best so I wouldnt doubt it if it ISCSI didnt actually make it into the next version.

High, 100% OT, but ESX3, which is now public beta, supports iscsi rather well. It also supports NFS. And yes, they integrated a TCP stack and the iscsi SW initiator and NFS stuff all into the VMkernel. Check out www.vmware.com for more about ESX or mail me off-list. Enough of this OT, please.
