Hmm, I'm stuck with a meta issue. I checked out the KVM tree[1] on L0, applied your patch and built[*] the Kernel, and booted into it. Boot fails and drops into a dracut shell on because: . . . dracut-initqueue[3045]: Warning: Cancelling resume operation. Device not found. [ TIME ] Timed out waiting for device dev-ma...per910\x2d\x2d02\x2droot.device. [DEPEND] Dependency failed for /sysroot. [DEPEND] Dependency failed for Initrd Root File SyWarning: /dev/disk/by-uuid/4ccddb2d-4d63-4fce-b4d4-9b2f119a30cc does not exist . . . I saved the report from /run/initramfs/rdsosreport.txt here[2]. Then, I did another test: - Rebooted into Kernel 3.20.0-0.rc0.git5.1.fc23.x86_64 on physical host (L0). - In L1, checked out the KVM tree, applied your patch and built Kernel[*] from the current KVM tree and booted into the newly built one, here too, I'm thrown into a dracut shell [1] git://git.kernel.org/pub/scm/virt/kvm/kvm.git [2] https://kashyapc.fedorapeople.org/temp/kernel-boot-failure.txt [*] Exactly, I built it this way: # Clone the tree $ git://git.kernel.org/pub/scm/virt/kvm/kvm.git # Make a new branch: $ git checkout -b nvmx_test $ git describe warning: tag 'for-linus' is really 'kvm-3.19-1' here for-linus-14459-g49776d5 # Make a config file $ make defconfig # Compile $ make -j4 && make bzImage && make modules # Install $ sudo -i $ make modules_install && make install -- /kashyap -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
