Converting a Hyper-V VM to a Template

#scp CentOS_6.2_x64 xenhost:/var/run/sr-mount/a9c5b8c8-536b-a193-a6dc-51af3e5ff799/

15.Log in to the Xenserver and create a VDI the same size as the image.

[root@xenhost ~]# cd /var/run/sr-mount/a9c5b8c8-536b-a193-a6dc-51af3e5ff799 [root@xenhost a9c5b8c8-536b-a193-a6dc-51af3e5ff799]# ls -lh CentOS_6.2_x64 -rw-r--r-- 1 root root 10G Mar 16 16:49 CentOS_6.2_x64

[root@xenhost a9c5b8c8-536b-a193-a6dc-51af3e5ff799]# xe vdi-create virtual-size=10GiB sr- uuid=a9c5b8c8-536b-a193-a6dc-51af3e5ff799 type=user name-label="Centos 6.2 x86_64" cad7317c-258b-4ef7-b207-cdf0283a7923

16. Import the image file into the VDI. This may take 10–20 minutes.

[root@xenhost a9c5b8c8-536b-a193-a6dc-51af3e5ff799]# xe vdi-import

filename=CentOS_6.2_x64 uuid=cad7317c-258b-4ef7-b207-cdf0283a7923

17.Locate a the VHD file. This is the file with the VDI’s UUID as its name. Compress it and upload it to your web server.

[root@xenhost a9c5b8c8-536b-a193-a6dc-51af3e5ff799]# bzip2 -c cad7317c-258b-4ef7-b207-

cdf0283a7923.vhd > CentOS_6.2_x64.vhd.bz2

[root@xenhost a9c5b8c8-536b-a193-a6dc-51af3e5ff799]# scp CentOS_6.2_x64.vhd.bz2

webserver:/var/www/html/templates/

13.12. Converting a Hyper-V VM to a Template

To convert a Hyper-V VM to a XenServer-compatible CloudPlatform template, you will need a standalone XenServer host with an attached NFS VHD SR. Use whatever XenServer version you are using with CloudPlatform, but use XenCenter 5.6 FP1 or SP2 (it is backwards compatible to 5.6). Additionally, it may help to have an attached NFS ISO SR.

For Linux VMs, you may need to do some preparation in Hyper-V before trying to get the VM to work in XenServer. Clone the VM and work on the clone if you still want to use the VM in Hyper-V. Uninstall Hyper-V Integration Components and check for any references to device names in /etc/fstab:

1.From the linux_ic/drivers/dist directory, run make uninstall (where "linux_ic" is the path to the copied Hyper-V Integration Components files).

2.Restore the original initrd from backup in /boot/ (the backup is named *.backup0).

3.Remove the "hdX=noprobe" entries from /boot/grub/menu.lst.

4.Check /etc/fstab for any partitions mounted by device name. Change those entries (if any) to mount by LABEL or UUID. You can get that information with the blkid command.

The next step is make sure the VM is not running in Hyper-V, then get the VHD into XenServer. There are two options for doing this.

Option one:

1.Import the VHD using XenCenter. In XenCenter, go to Tools>Virtual Appliance Tools>Disk Image Import.

2.Choose the VHD, then click Next.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
