This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux release for currently deployed products. This request is not yet committed for inclusion in a release. Testing shows that this problem is reproducible even with 6.2. Testing images uses different configuration - 6.2 has xen_emul_unplug=never and 6.3 uses xen_emul_unplug=ide-disks. When using pv-on-hvm drivers with emulated drivers unplugged, block drive does not find the disk so system fail with no hard disk. Can you attach the Xen domain configuration file (either the XML for libvirt, or the one for xm)? Any standard config file works, I'm reproducing the problem with this xen config: name = "bz849895_3" uuid = "22e45cd6-8bdd-61e5-7679-d3e1e8a7afd1" maxmem = 1024 memory = 1024 vcpus = 2 builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" pae = 1 acpi = 1 apic = 1 localtime = 0 on_poweroff = "destroy" on_reboot = "restart" on_crash = "preserve" device_model = "/usr/lib64/xen/bin/qemu-dm" sdl = 0 vnc = 1 vncunused = 1 keymap = "en-us" disk = [ "file:/var/lib/xen/images/lws/bz849896/RHEL-Server-6.2-64-hvm2.qcow,hda,w", ",hdc:cdrom,r" ] vif = [ "mac=00:16:3e:6c:e3:0c,bridge=virbr0,script=vif-bridge" ] parallel = "none" serial = "pty" Important part is disk configuration. There's 4 possible settings: 1] file:/var/lib/xen/images/lws/bz849896/RHEL-Server-6.2-64-hvm2.qcow,hda,w 2] file:/var/lib/xen/images/lws/bz849896/RHEL-Server-6.2-64-hvm2.qcow,xvda,w 3]

Ok, one day of testing to remember we decided to not backport change for backing file. So we support only qcow on qcow (unlike the upstream that supports qcow on raw). Using raw as backing file is not supported and fails everytime. I have to check why the img2qcow scenario fails. Can you please retest the Scenario 3 with ensuring tap:qcow is used for disk configuration. It's working for me. You can't use file: as you're trying to use only pv-on-hvm - image does not go through proper blktap path and is not opened correctly.

Failures was caused by using unsupported configurations: 1.) Using raw image as backing file is not supported. Only qcow image is supported as backing file 2.) Using qcow image with loopback configuration and pv-on-hvm drivers only. This can't work as image is not properly handled by blktapctrl deamon. |
