CentOS-6.6 virt-manager 0.9.0 I have cloned a template server with a 32GB virtio HDD already defined and am attempting to add additional virtio disks. The basic cloned system boots without error. If I create a virtio disk with 32000/32000 megabytes I can add it and the system reboots; providing that I do not first create a partition: fdisk -l /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03 Disk /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03: 33.6 GB, 33554432000 bytes 255 heads, 63 sectors/track, 4079 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x02ec08ff Device Boot Start End Blocks Id System However, in that event I cannot see the new disk: /dev/mapper/vg_inet01b-lv_root / ext4 defaults 1 1 UUID=218fd81f-6811-4965-b8d5-b0098a569598 /boot ext4 defaults 1 2 /dev/mapper/vg_inet01b-lv_tmp /tmp ext4 defaults 1 2 /dev/mapper/vg_inet01b-lv_log /var/log ext4 defaults 1 2 /dev/mapper/vg_inet01b-lv_spool /var/spool ext4 defaults 1 2 /dev/mapper/vg_inet01b-lv_swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 If I do partition the disk thus: fdisk -l /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03 Disk /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03: 33.6 GB, 33554432000 bytes 109 heads, 61 sectors/track, 9856 cylinders Units = cylinders of 6649 * 512 = 3404288 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x02ec08ff Device Boot Start End Blocks Id System /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03p1 1 9857 32766976 83 Linux Then when I boot the vm it fails with a kernel panic. If I remove the disk or remove the partition from that disk then the cloned system will boot successfully. Does anyone have any idea what is going on and how to fix it? -- *** E-Mail is NOT a SECURE channel *** James B.
