We have tested xen 3.0.0 (ChangeSet 8241) on Intel S3E3141 SDP. It has 4 sockets, each socket is dual core, dual thread. In general, VMX works fine as IA32/IA32E guest on both IA32/IA32E service OS. IA32 Windows are bootable.We can boot IA64 guest after changing the build config file of IA64. IA64 works better on RHEL4U2 than on RHEL3 Here is the main issues that we found in the testing: + There is no VMX information in xen 3.0 user manual + Evtchn delay (may lost) issue on big SMP machine causes a black QEMU window when startup IA32&IA32e VMX on IA32e host + xen0 booting fails on Xen 3.0.0 IPF version. Need to change the build config file to make it work + VTI domain will hang after booting up several minutes on EL3. + vmx''s network broken about every 10 minutes when there are 2 or more vmx + Install FC2-IA32 on VMX will crash service OS + Cannot install IA32e guest OS from CDROM + Cannot Install SuSE10-IA32 guest OS from CDROM + The second Windows XP guest will be unstable + HCT stress may make Windows blue screen + vcpu-pin will hang service OS. + On IA-32e, service os and guest os have different time zone, but the same time value. + In IA-32e guest on IA-32e service os, can''t type numbers in text console through the number key on the right side of the keyboard. + If use vnc (vnc=1 and vncviewer=1) to create a vmx and startx in vmx.The Xwindows'' response to keyboard and mouse will be very slow and can''t switch to text console. We also have tests for binaries in http://www.xensource.com/xen/downloads/. Basically VMX does not work with these binaries. The main issues that we found are: + Most Xen3.0 binaries dosn''t have vmxload and thus cannot startup vmx, except IA32/PAE SMP tarball. We can create VMX from IA32 tarball. + xen0 keep rebooting on DP platform after install xen 3.0 for rhel4u1rpm + Create vmx guest on PAE host cause service os reboot from PAE tarball + IA32e tarball only support ext2 file system.
