    • Note: If the virtual datacenter is changed, the migration zone must also be changed
  • Change migration zone
  • Disable automatic recovery
  • Disable VT-x flag
  • Edit timezone configuration
  • Edit boot order

Adding a vNIC

  1. Select Add vNIC from the Actions drop-down menu or click Add vNIC in the Networking section of the instance's Profile page.
  2. Enter the desired settings for the vNIC.
  3. Click Add vNIC

Note: This can only be done while the instance is shut down.

Adding a vDisk

  1. Select Add vDisk from the Actions drop-down menu or click Add vDisk in the Storage section of the instance's Profile page.
  2. To add a new vDisk:
    1. Click New vDisk.
    2. Enter a name and size for the vDisk.
    3. Click Add vDisk.
  3. To add a vDisk clone:
    1. Click Add vDisk clone.
    2. Select the snapshot and vDisk you wish to clone and attach to this instance.
    3. Click Clone and Attach to Instance.
      • See here for more information on cloning and attaching vDisks.

Resizing a vDisk

  1. On the application instance's Profile page, click beside the vDisk you want to resize and click Edit Size.
  2. Enter the new size of the disk.
    • Note: The new size must be larger than the current size.
  3. Click Save.

After resizing the disk for Windows:

  1. Console into the Windows instance.
  2. Open Disk Management. The disk that was resized will show Unallocated space.
  3. To create a new volume in the Unallocated space:
    1. Right-click on the Unallocated space and select New Simple Volume.
    2. Click Next and enter the volume size
    3. Click Next and assign a drive letter to the new volume.
    4. Click Next, select formatting options and assign a volume label.
    5. Click Next and Finish.
  4. To extend the current volume into the Unallocated space:
    1. Right-click on the volume and select Extend Volume.
    2. Click Next and enter the amount of space to add to the volume.
    3. Click Next and Finish.
  5. Verify the partition is aligned and realign it if necessary:
    1. Open System Information (msinfo32).
    2. Expand Components, then Storage, and click on Disks.
    3. For each disk, make note of the Size in bytes, the Partition Size in bytes, and the Partition Starting Offset in bytes.
    4. Check for misalignment:
      1. If you have multiple partitions, add the add the Partition Size (bytes) to the Partition Starting Offset (bytes). Subtract this value from the Partition Starting Offset (bytes) of the subsequent partition. You should get either 0 or a positive number.
      2. For the last partition on the disk, add the Partition Size (bytes) to the Partition Starting Offset (bytes). Subtract this value from the disk Size (bytes). You should get either 0 or a positive number.
      3. If you get a negative number for either of these, it means your partition is misaligned by that number of bytes: it's either overlapping another partition or it ends beyond the end of the disk.
    5. Shrink the volume:
      1. Open Disk Management.
      2. For each partition that is misaligned, right click on it and select Shrink. Shrink the volume by the amount by which it's misaligned or more. That is, take the negative number you calculated in the previous step and divide it by 1,048,576 to get the size in MB, then shrink the volume by at least that amount.

After resizing the disk for Linux:

  1. Console into the Linux instance.
  2. To create a new, ext4 partition /dev/sdb2 on disk /dev/sdb:
    1. Check how many drives are installed: fdisk -l | grep '^Disk'
    2. Add a partition to the disk:
      • fdisk /dev/sdb
      • Type p to use the partitioner, n to create a new partition, and select your preferred settings when prompted.
      • Type w to save the partition.
    3. Format the disk: mkfs.ext4 /dev/sdb2
    4. Create a mount point and mount the partition:
      • mkdir /disk2
      • mount /dev/sdb2 /disk2
    5. Edit fstab so the new partition automatically mounts to /disk2 on reboot:
      • vi /etc/fstab
      • Type i to edit the file.
      • Add a line: /dev/sdb2 /disk2 ext4 defaults 1 2
      • Enter ESC and type :wq to write the changes and save the file.
  3. To expand an existing, ext4 partition /dev/sdc1 on disk /dev/sdc that's mounted to /disk3:
    1. Unmount the partition: umount /disk3
    2. Expand the partition by deleting and recreating it without deleting the data:
      • fdisk /dev/sdc
      • Print the current partitions: p
      • Delete the partition: d
        • If multiple partitions are present, select the desired partition when prompted
      • Recreate the partition: Type p to use the partitioner, n to create a new partition, and select your preferred settings when prompted.
      • Type w to save the partition.
    3. Expand the ext4 filesystem: resize2fs /dev/sdc1
