Subject: runqemu: Use virtio to mount cdrom drives
X-Git-Tag: 2017-10~474
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=f59e729f98ef9b506b0cfdc415567e03ec87f2a9;p=openembedded-core.git

runqemu: Use virtio to mount cdrom drives

The IDE driver in the kernel is fragile and in 4.12 is causing backtraces.
To unblock 4.12 kernel merging use the virtio CD driver instead to mount
iso images which should be faster and more stable.
