[Xen-devel] Upstream qemu not working with latest Xen staging unstable
Hi, all This problem has been brought up once by Daniel Castro. http://marc.info/?l=xen-devel&m=130795535706323&w=2 But he didn''t post the complete log. Now I''m able to reproduce this problem. I have my qemu log below. I think this is a Xen problem. I use Anthony''s candidate/xenpv-support branch and test with several Xen reversions. Xen staging unstable r23546, fail Xen staging unstable r23475 (I want to work with IanJ''s libxl patch, that''s why I choose this reversion), fail Xen unstable r23369, succeed This is not a thorough regression test though. FYI. Wei. -----qemu log----- char device redirected to /dev/pts/1 Warning: more nics requested than this machine supports; some have been ignored VNC server running on `127.0.0.1:5900'' qemu: hardware error: register_ioport_write: invalid opaque for address 0xc000 CPU #0: EAX=00000000 EBX=00000000 ECX=00000000 EDX=00000633 ESI=00000000 EDI=00000000 EBP=00000000 ESP=00000000 EIP=0000fff0 EFL=00000002 [-------] CPL=0 II=0 A20=1 SMM=0 HLT=1 ES =0000 00000000 0000ffff 00009300 CS =f000 ffff0000 0000ffff 00009b00 SS =0000 00000000 0000ffff 00009300 DS =0000 00000000 0000ffff 00009300 FS =0000 00000000 0000ffff 00009300 GS =0000 00000000 0000ffff 00009300 LDT=0000 00000000 0000ffff 00008200 TR =0000 00000000 0000ffff 00008b00 GDT= 00000000 0000ffff IDT= 00000000 0000ffff CR0=60000010 CR2=00000000 CR3=00000000 CR4=00000000 DR0=00000000 DR1=00000000 DR2=00000000 DR3=00000000 DR6=ffff0ff0 DR7=00000400 EFER=0000000000000000 FCW=037f FSW=0000 [ST=0] FTW=00 MXCSR=00001f80 FPR0=0000000000000000 0000 FPR1=0000000000000000 0000 FPR2=0000000000000000 0000 FPR3=0000000000000000 0000 FPR4=0000000000000000 0000 FPR5=0000000000000000 0000 FPR6=0000000000000000 0000 FPR7=0000000000000000 0000 XMM00=00000000000000000000000000000000 XMM01=00000000000000000000000000000000 XMM02=00000000000000000000000000000000 XMM03=00000000000000000000000000000000 XMM04=00000000000000000000000000000000 XMM05=00000000000000000000000000000000 XMM06=00000000000000000000000000000000 XMM07=00000000000000000000000000000000 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I did not update this branch since a while. But if you just want to run HVM guest, you could use "my" branch "xen-next", as it will be merge (soon I hope) in qemu-uptream. If you need the patches in candidates/xenpv-support, eithier merge it or cherry-pick the patch ;).

Hopefully it will also help everybody that is trying to setup the new qemu on xen. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
