[Bug 1065628] Re: pci device not reset (passthrough)

[Gerben]

Fresh start:
@pci-02:~$ lsusb 
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 002: ID 045e:0750 Microsoft Corp. Wired Keyboard 600
(On the KVM host the KVM process is nice flat, e.g. 1% cpu)

Power off and again starting using virsh start...
@pci-02:~$ lsusb 
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
(On the KVM host the KVM process uses 67% cpu continuously, but no cpu used shown in the kvm client, nothing started there either.)

KVM Host top:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
