Title:
qemu cannot run twice
Status in QEMU:
Invalid
Bug description:
After using qemu with gpu passthrough and then shutting down windows 7
properly I cannot boot windows 7 a second time.
Only a full reboot of linux fixes this issue.
Qemu appears to corrupt something in linux when exiting.
I get no error messages but windows 7 never finishes booting during the 2nd
try.
Apparently I do try to run vfiobind each time the script is run.
Wondering if rerunning vfiobind can cause an issue?
