h2. Known Issues and Limitations
h4. Solaris hosts must have adequate swap space. (Bug ID 1225025)
Solaris hosts running xVM VirtualBox *must* have swap space equal to, or greater than the host's physical memory size. For example, 16GB physical memory would require at least 16GB swap. This can be configured during a Solaris 10 install by choosing a 'custom install' and changing the default partitions.
For existing Solaris 10 installs you will need to create a swap image file on the local filesystem and mount it. The swap file image size should be: Physical Memory - Current Swap = Additional Swap Required. For example, 16GB physical memory - 1GB = 15GB of additional swap required. To add the swap to your system:
*For ZFS:*
{code:borderColor=#ccc}
# zfs create -V 16gb _<ZFS volume>_/<new_swap_volume>
# swap -a /dev/zvol/dsk/_<ZFS volume>_/<new_swap_volume> {code}
To have the swap mounted after a reboot, add the following line to {{/etc/vfstab}}:
{code:borderColor=#ccc}
/dev/zvol/dsk/_<ZFS volume>_/<new_swap_volume> - - swap - no -{code}
*For UFS:*
{code:borderColor=#ccc}
# mkfile 15g /path/to/swap.img
# swap -a /path/to/swap.img{code}
To have the swap mounted after a reboot, add the following line to {{/etc/vfstab}}:
{code:borderColor=#ccc}
/path/to/swap.img - - swap - no -{code}
h4. Memory for ARC cache should be restricted to a lower limit when using ZFS on S10u7. (Bug ID 6844780)
When all VDI components (VDI host, xVM VirtualBox host, and ZFS storage) are installed on a single box (x86 platform, running S10u7), xVM VirtualBox will not be able to start any desktops.
*Cause* - ZFS uses any memory available (up to the limit) for an ARC cache. If other programs try to access the memory, ZFS should release it. Unfortunately, VDI evaluates the memory before trying to start a virtual machine and recognizes that not enough memory is available to start the virtual machine. Full details are available here [http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#ARCSIZE].
*Solution* - The memory for the ARC cache can be limited to a max value by adding an entry in /etc/systems file.
For example, to restrict the memory to 2GB, in {{/etc/system}} add:
{code:borderColor=#ccc}
set zfs:zfs_arc_max = 2147483648 {code}
It has been verified that keeping this value to as low as 512MB and importing a file of 2.7G will work as desired.
h4. Desktops cannot use 'Host Networking' unless VirtualBox has been configured to run as root. (Bug ID 6839450)
Virtual machines cannot be started with host networking unless the VirtualBox web service runs as root.
h4. During log-off, VirtualBox desktops do not go into idle state when settings are 'Host Networking - WinRDP'. (Bug ID 6837283)
Desktop never go to the idle state and remain in used state forever and hence do not get recycled.
h4. VDI Host Overload (Bug ID 6810444)
In case you see a blank page when login in to the administration ui it's likely that database problems are the root cause. You may for instance see "Error 157" in the database log files in '/var/opt/SUNWvda/mysql-cluster' of the primary or one of your secondary hosts.
*Cause\-* When using the VDI MySQL Cluster database, the first two VDI secondary hosts run the MySQL Cluster data nodes in addition to a MySQL SQL node, SRSS, SRWC, VDI, etc. MySQL Cluster is sensitive to resource shortages. The expected load to the MySQL Cluster data nodes is small, so the MySQL processes should be able to cope under typical loading. However, if you have too many Sun Ray sessions on each of the first two Sun Ray secondaries, you may see this error.
*Solution\-* Check the load on the concerned hosts and if it is high, reduce the load on this host e.g. by reducing the number of SRSS sessions hosted. Restart the SQL node running on the concerned host
h4. Using the VDI CLI in parallel with the Admin Web GUI. (Bug ID 6770476)
Using the [vda CLI|The vda Command] to modify some data, while having an Admin Web UI session running, might generate errors in the Web Admin UI and log you out. At following login, the Web Admin UI will be working fine again.
h4. Limitations with VDI hosts running on SPARC. (Bug ID 6812848)
* Only one storage is supported with Solaris SPARC VDI hosts.
* The 'duplicate' action fails with Solaris SPARC VDI hosts.
*Cause\-* Sun VDI 3.0 does not support copying one iSCSI volume to another iSCSI volume via Java in Solaris SPARC VDI hosts.
h4. Sun Open Storage fails after a software update. (Bug ID 6826006)
* Do not update the software of a Sun Open Storage after it has been added to VDI 3.0. Any management action of VDI 3.0 fails afterwards.
h4. OpenSolaris Update causes SSH to the storage box to fail. (Bug ID 6812829)
After doing a 'pkg image-update' on an OpenSolaris host used for xVM VirtualBox storage, VDI can no longer SSH to the box. The following error is seen:
{code:none}
Caused by: com.jcraft.jsch.JSchException: Algorithm negotiation fail
at com.jcraft.jsch.Session.receive_kexinit(Session.java:510)
at com.jcraft.jsch.Session.connect(Session.java:285)
at com.sun.vda.service.vbox.SshServer.executeCommand(SshServer.java:331)
... 40 more
{code}
Normal SSH via the command line continues to work fine.
*Cause\-* Changes have been made to how the sshd negotiates the ciphers between version 101b and 108 of OSOL.
*Solution\-* We require the customer to use the release version of OSOL 2008.11 (101b). Any upgrades are not supported and need to get clearance from us first.
A fix in this particular case is to activate the 'Ciphers' line in {{/etc/ssh/sshd_config}} and to restart the ssh service.
h4. vb-install script fails to install xVM VirtualBox package. (Bug ID 6814023)
If you uninstall xVM VirtualBox and want to reinstall it, the installation may fail.
*Cause\-* Some xVM VirtualBox processes may still remain even after removal.
*Solution\-* Reboot the xVM VirtualBox host to kill any remaining processes.
h4. Cloned virtual machines have lower resolution than the xVM VirtualBox virtual machine templates. (Bug ID 6815380)
The cloned VM has a blurry desktop image because it has a lower (8-bit) resolution compared to the original (32-bit) virtual machine.
h4. Migrating large numbers of pools from VDI 2.0 to 3.0 fails. (Bug ID 6819562)
Sometimes when migrating two or more pools from VDI 2.0 to VDI 3.0 the first pool will succeed and the next ones will fail.
*Cause\-* A misconfiguration in the vda-migrate tool.
*Solution\-* It is recommended not to migrate several pools simultaneously from VDI 2.0 to VDI 3.0 (a patch for this issue will be available soon).
h4. Importing VDI 2.0 data into VDI 3.0 fails if pool's recycle policy is 'Destroy'. (Bug ID 6818383)
*Cause*\- The "Recycling Policy" value 'destroy' in VDI 2.0 became 'delete' for VDI 3.0.
*Solution\-* Edit the exported text properties file ('migrate_svdc_1.?'). It should be located in the directory which was used to export previous Sun VDI data. Find all the lines which end with "pool.recyclepolicy=Destroy" and modify them to "pool.recyclepolicy=Delete".
