[Qemu-devel] [Bug 882358] Re: device assignment doesn't work: "error: requires KVM support"

[Yongjie Ren]

This is because kvm is not enabled by default even if I add KVM support when 
configuring qemu. 
Now it got fixed by the following commit.

Revert "qemu-kvm: set default accelerator via target.conf"

This reverts commit a5c40eb1aa929a03157252db7337bc4ddd2435be.

Jan says:

"Unless you fully install qemu, that conf is not picked up (or an older
version is used). I'd still like to see this working with qemu started
from a build directory..."

Title:
  device assignment doesn't work: "error: requires KVM support"

Status in QEMU:
  Fix Released

Bug description:
  qemu.git commit:8843cf40c0f482949e6ae9d0119e45d6b96fe890

  I met the following error when do device assignment with qemu in kvm host. 
  ./x86_64-softmmu/qemu-system-x86_64 -smp 2 -m 1024 -device 
pci-assign,host=0e:00.0 -hda /root/jay/rhel6u1.img
  qemu-system-x86_64: -device pci-assign,host=0e:00.0: pci-assign: error: 
requires KVM support
  qemu-system-x86_64: -device pci-assign,host=0e:00.0: Device 'pci-assign' 
could not be initialized

  ./x86_64-softmmu/qemu-system-x86_64 -device ? 2>&1 | grep -i pci-assign
  -----------------name "pci-assign", bus PCI, desc "pass through host pci 
devices to the guest"
  When configuring the qemu, it prints "KVM support       yes".    My qemu 
configuration log and compiling log are attached.

  But commit edbb7c0d doesn't have this issue.
