After more investigation (comparation of the machine description between the ubuntu qemu 2.3 and 2.5), I have seen that in 2.3, the utopic machine is a kvm-2.3 machine while it's a kvm-2.5 machine is 2.5 when it should be kvm-2.3 too.
I will provide a debdiff once I have validated my change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641532 Title: Unknown ramblock "/rom@etc/acpi/rsdp", cannot accept migration To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1641532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
