Note that that fix, verbatim, is in v0.12.5 which is currently in maverick. It is later quietly removed, and ISTR previously confirming that it had been replaced by a proper fix (but can't find that right now). So it is fixed in maverick. -- qemu-system-x86_64 segfaults if using -no-kvm with -m 4096 or greater https://bugs.launchpad.net/bugs/602539 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

** Description changed: Binary package hint: qemu-kvm Latest Ubuntu 10.04 amd64. I have a FreeBSD guest I had running quite slowly with the kvm-intel module loaded, so I shut down the guest, and passed the -no-kvm flag to kvm. Much to my surprise, I experienced an immediate segmentation fault: $ qemu-system-x86_64 -no-kvm -vnc :0 -hda fbsd_dev -m 4096 pci_add_option_rom: failed to find romfile pxe-rtl8139.bin Segmentation fault (core dumped) In contrast: $ qemu-system-x86_64 -no-kvm -vnc :0 -hda fbsd_dev -m 4095 pci_add_option_rom: failed to find romfile pxe-rtl8139.bin [runs happily forever] I'm presuming this is some mishandled behavior of qemu having a limit of memory being 4096m when not using VT bits or somesuch, but it was quite disruptive, and it didn't occur to me to try varying the memory amount for most of a day.

Thanks you for reporting this bug and helping to make Ubuntu better. And thanks especially for finding the specific patch. This patch should probably get cherry-picked into the lucid qemu-kvm version. I've set importance to low since the fix is to refuse the disallowed arguments. ** Changed in: qemu-kvm (Ubuntu) Status: New = Confirmed ** Changed in: qemu-kvm (Ubuntu) Importance: Undecided = Low ** Changed in: qemu-kvm (Ubuntu) Milestone: None = lucid-updates ** Changed in: qemu-kvm (Ubuntu) Assignee: (unassigned) = Serge Hallyn (serge-hallyn) -- qemu-system-x86_64 segfaults if using -no-kvm with -m 4096 or greater https://bugs.launchpad.net/bugs/602539 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
