Hi all, I'm trying out kvm and running into problems reported as "exception 12" and "exception 13" and segfaults. I'm using a HP Compaq dc7700p system with an Intel Q965 chipset running x86_64 Ubuntu Feisty.
When I try to run either kvm-16 included with Feisty or my own kvm-19 compiled from source, I get an exception like: exception 13 (0) rax 000000000000001f rbx 000000000006bffa rcx 0000000000033c25 rdx 0000000000000000 rsi 000000000006bffa rdi 000000000004ebf3 rsp 0000000000007bd6 rbp 000000000006bfe4 r8 0000000000000000 r9 0000000000000000 r10 0000000000000000 r11 0000000000000000 r12 0000000000000000 r13 0000000000000000 r14 0000000000000000 r15 0000000000000000 rip 000000000000145f rflags 00033046 cs 4004 (00040040/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds 4004 (00040040/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) es 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ss 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) fs 0080 (00000800/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) gs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) tr 0000 (18850000/00002088 p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) ldt 0000 (00000000/0000ffff p 1 dpl 0 db 0 s 0 type 2 l 0 g 0 avl 0) gdt 40620/f idt 0/3ff cr0 60000010 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 Aborted (core dumped) and lots of messages such as: [77221.746966] rtc: lost some interrupts at 1024Hz. in my syslog. Similar symptoms have been reported by others as: https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/103665 and https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/107172 I should mention that kernels 2.6.19 and 2.6.20 seem to have a bug that causes this machine (and 3 other identical machines) to lose clock ticks at the rate of 3 seconds per minute. (This problem seems to have been resolved in 2.6.21-rc5.) This may or may not be related to the kvm problems. I couldn't see any simple switch to configure to compile with debug symbols, but if someone can tell me how to do this, I'll use gdb to post a backtrace. Is there anything else I can report to pinpoint the problem? ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
