Installing Kerio Control on the Xen Cloud Platform virtualization system, how to solve the problem of new versions of kerio?

Question

Xen

Good day to all, there are servers at the enterprise with XCP installed on them, there is a need to transfer the Kerio Control software built on the basis of CentOS to the virtualization system, but if there were no problems with versions of previous years, then 8 versions of Kerio no longer want to be installed correctly in as virtual machines or run after a banal transfer of virtual media. In the first case, the installer reports that no hard disk was found for installation; in the second case, the system bootloader, after its initialization, does not see the hard disk partitions with the operating system. As far as I know, the latest versions of Kerio have changed the bootloader (quite likely to grub), but Debian with the same bootloader feels great on the same farm. XCP I use versions 6.1, Kerio Control 8.3.
In addition, I can say that a correctly working Kerio 6 version, if it is upgraded to version 8, stops working with the same symptoms as the one installed in Virtual Box in a VHD container and transferred to XCP using XenCenter.
Reminding me that Kerio does not have support for XCP or Citrix virtualization systems is not worth it, just like telling me that everything works fine for you, I would like to read the solution for my problem. It is possible to somehow replace the bootloader with grub2 or patch the one that is. Perhaps there are some builds of Kerio with fixed problems. Thanks in advance for your replies.

Answer 1

Kerio 8.5.3 the same problem (the installer does not see the virtual disk), I did not find a ready solution in the search engines. I began to compare the already installed 7.3.2 (kernel 2.6.38 - further k7) with 8.5.3 (kernel 3.12.9 - further k8). According to the article , starting from 2.6.36, PVHVM mode should be enabled, but in my VMs, k7 remains in HVM mode and does not use xen drivers. k8, in turn, starts switching to PVHVM mode, about which it writes - "Booting paravirtualized kernel on Xen HVM (description here), but there is no xen-blkfront.ko responsible for block devices in the image. Although the xen-netfront.ko module is present and the network interfaces are up. My knowledge is not yet sufficient to embed xen-blkfront.ko into an existing image or set the virtual machine to stay on a pure HVM. I will be glad for any help.

Hello!
If you install Kerio control appliance on xenserver and select Windows server 2008 r2 in the templates, then you can't install xenserver tools. Is there a solution to the problem?
Thank you!
