Steven Hand wrote: Hi Ed, any chance you can test with debug=y ? The back-traces aren't really very useful otherwise. These are automated builds and tests that run each night. We don't normally build a debug XEN as we try and test the bits a customer would run. If these backtraces are useful in the release build how will we diagnose crashes on a customer's site? It'd also be good to know what the h/w platform is - AMD or Intel. This hardware and guest information is in the test report but I've added it here as well. Also I tried booting the guests with/without the kernarg noapic, no difference. Did you need more guest config information that this? I can send you the actual config if you like but these are the key settings. Test Configuration: Dell Precision WorkStation 380, Dual Core, 2GB, 3 SATA (Intel VT) 64bit XEN Hypervisor on a RHEL4U2 64bit root (/dev/sda) 32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb) pae=1(smp) pae=0(up), acpi=1, apic=1 kernargs noapic 64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc) pae=1, acpi=1, apic=1 kernargs noapic Summary: Changeset 11616 - NEW: 32bit SMP HVM Guests hang on boot: "Uncompressing Linux... OK booting the kernel" (failure.6)By '32bit' do you mean PAE? What guest is this? What's the guestconfig? I cannot reproduce this myself on 11616... RedHat 4 SMP kernels as shipped are PAE, while their UP kernels are non-PAE. The appropriate setting is used in HVM config depending on which kernel I'm booting. - NEW: 64bit UP and SMP guests crash domain on boot: domain_crash_sync called from vmx.c:2268 (failure.5)This looks like the same bug to me, also cannot repro. Once more, guest + guest config info would be useful. Hardware and guest information is in the report, see above. 2. XEN crash on an xm destroy of a dead guest 32bit SMP HVM guest: Fatal page fault - put_page_from_l1e+0x85/0x140Hmm - when you say "GUEST CRASHED IN GUEST CONSOLE", what actuallyhappens? Can you post the output? Have you seen this post 11486, or has it gone away? I did not have the guest configured for serial console so the stack traces scrolled by on the guests VGA console. If I can reproduce this I'll capture the serial console output and post it. I did not reproduce this yesterday on c/s 11600. Can you let us know what guest and guest config you are using? In report. Testing with a debug build of Xen will also help.3. XEN crash running ltp "mtest01 -p80" on 32bit SMP HVM guest: BUG at multi.c:2864 from sh_page_fault__shadow_3_guest_3This is probably the same as #2, just taking a different path throughXen. Have you seen this post 11486, or has it gone away? [Again: guest, guest config, debug xen] Again in report. This particular crash was not reproduced yesterday on c/s 11600. 4. XEN crash running ltp "mtest01 -p80" on 32bit SMP HVM guest: BUG at multi.c:3958 from sh_clear_shadow_entry__shadow_3_guest_3May be related to #2 and #3. This bug was reproduced on c/s 11600. [Again: guest, guest config, debug xen] Again in report. cheers, S.
