Sounds unlikely, but symptoms look like this is the case. Yes, maybe. I'm currently building a debug version that has support for TCG block tracing enabled. Should get us closer to the crash.

Sounds unlikely, but symptoms look like this is the case. Looks like the old story again: extboot tries to write to ROM (old_int13 and old_int19 variables). That happens to work due to KVM limitations, but breaks once true protection is established. Don't we have some heap managed by Seabios that extension ROMs can use?

Hi, Same problem here qemu-kvm-0.12.x hangs if I have at the same time -no-kvm and file=essai-slitaz.raw,if=ide,index=0,boot=on sometime with the message below but qemu-kvm with -no-kvm and without boot=on option for the file parameter, works qemu-kvm with boot=on option and kvm enable works. (kvm-kmod is 2.6.32.7) Unfortunatly, I am using libvirt which always set boot=on on the file parameter, so I have to downgrade qemu-kvm to 0.11 version Jacques Landru == qemu: fatal: Trying to execute code outside RAM or ROM at 0xe100 EAX=1fec EBX=000255aa ECX=fffe EDX=8381 ESI=0006 EDI=0201 EBP=77e9 ESP=fffe EIP=e0f2aba5 EFL=0002 [---] CPL=0 II=0 A20=1 SMM=0 HLT=0 ES = 9300CS =d544 000d5440 9e00SS = 9300DS = 9300FS = 9300 GS = 9300 LDT= 8200 TR = 8b00 GDT= 8e84 0027 IDT= 03ff CR0=0010 CR2= CR3= CR4= DR0= DR1= DR2= DR3= DR6=0ff0 DR7= CCS=1fec CCD=2060 CCO=ADDB FCW=037f FSW= [ST=0] FTW=00 MXCSR=1f80 FPR0= FPR1= FPR2= FPR3= FPR4= FPR5= FPR6= FPR7= XMM00= XMM01= XMM02= XMM03= XMM04= XMM05= XMM06= XMM07= Aborted -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
