Test with qemu-kvm-1.5.3-67.el7.x86_64, not met this issue.
initrd is not updated after guest device configuration change, that may make a different device path, or missing virtio_blk module when booting. Could you show the output of "lsmod | grep virtio" and "ls -R /dev/disk /dev/mapper" after it drops to dracut shell? Fam This is a duplicate of bug 1127151 but just the other way around. So close it too. *** This bug has been marked as a duplicate of bug 1127151 *** (In reply to ShupingCui from comment #1) > Created attachment 926005 [details] > serial log > > Test with qemu-kvm-1.5.3-67.el7.x86_64, not met this issue. This is an open question that needs some more investigation. Fam Can't reproduce after testing again with qemu-kvm-rhev-2.1.0-2.el7.x86_64. When generating initrd, during either system installation or kernel update, dracut takes care of installing *both* virtio-blk and virtio-scsi drivers into the initramfs image, as long as it finds itself inside a virtual machine. (that is detected with running `systemd-detect-virt --vm` in guest). This logic is guaranteed by the qemu module (/usr/lib/dracut/modules.d/90qemu). For both qemu-kvm and qemu-kvm-rhev, the output of systemd-detect-virt command is "kvm". I checked that in the test env, these look fine and work as expected. So interchanging the system disk type between virtio-blk and virtio-scsi for RHEL 7 guest should just work. If in some way it is broken and only one of the two drivers is present in initrd, systemd-detect-virt, dracut and anaconda are the points to check. Fam |
