Title:
Enabling KVM with recent QEMU builds from GIT hang at boot on Ubuntu
Precise AMD64 kernel 3.8.0
Status in QEMU:
Fix Released
Bug description:
When I compile QEMU from GIT and run it with
'./x86_64-softmmu/qemu-system-x86_64 -enable-kvm' it just hangs, the QEMU
screen stays black. (Everything else in the GTK UI is responsive though, I can
use the QEMU console as well.)
I'm running Ubuntu Precise with kernel 3.8.0-27-generic on an Intel Core2 Duo
P9500.
With bisecting, I found this commit caused the problem:
235e8982ad393e5611cb892df54881c872eea9e1 is the first bad commit

kvm: support using KVM_MEM_READONLY flag for regions
For readonly memory regions and rom devices in romd_mode,
we make use of the KVM_MEM_READONLY. A slot that uses
KVM_MEM_READONLY can be read from and code can execute from the
region, but writes will exit to qemu.
For rom devices with !romd_mode, we force the slot to be
removed so reads or writes to the region will exit to qemu.
(Note that a memory region in this state is not executable
within kvm.)
v7:
* Update for readable => romd_mode rename (5f9a5ea1)
