[Qemu-devel] [Bug 1243287] Re: [KVM/QEMU][ARM][SAUCY] fails to boot cloud-image due to host kvm fail
A workaround that we used was to rename dmidecode to /bin/true and .make it persistent. dpkg-divert --local --divert /path/dmidecode --rename --add /bin/true. But that is just a workaround, any code that maps() /dev/mem can cause these crashes. Is there a fix for this in the horizon ? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1243287 Title: [KVM/QEMU][ARM][SAUCY] fails to boot cloud-image due to host kvm fail Status in QEMU: Confirmed Bug description: On booting the cloud image using qemu/kvm fails with the following error: Cloud-init v. 0.7.3 running 'init' at Thu, 03 Oct 2013 16:45:21 +.

I did send a patch for dmidecode to exit gracefully if there is no bios or smbus before it did all the mmap() damage, but no one seemed interested in that patch.

[Qemu-devel] [Bug 1243287] Re: [KVM/QEMU][ARM][SAUCY] fails to boot cloud-image due to host kvm fail
Ubuntu kernels use CONFIG_STRICT_MEM which prevents access to physical mem other than BIOS and PCI region so that X or dmidecode tools can read this info. On a native ARM system since there is no BIOS (yet) this causes mmap() of /dev/mem to return a -1. But with KVM/QEMU emulating ARM (mach virt) on native ARM, mmap() /dev/mem does not return a -1 but returns a valid address (or what looks like a valid address). Could it be that kvm/qemu is not passing protections correctly for phy mem ? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1243287 Title: [KVM/QEMU][ARM][SAUCY] fails to boot cloud-image due to host kvm fail Status in QEMU: New Bug description: On booting the cloud image using qemu/kvm fails with the following error: Cloud-init v. 0.7.3 running 'init' at Thu, 03 Oct 2013 16:45:21 +.
