Hello, I am trying to install a centos with graphical environment but has not been possible. When uploading the iso to CloudStack I choose CentOS 6.4 64-bit, Other CentOS 64-bits, but it's not working for me :( the install process work with graphicall enviorement but then i restart the OS and the X not works any idea? thanks -- Hollman Eduardo Enciso R. http://algolibre.com @hollman

CentOS should work at least with the Vesa driver. If you are after graphical UI then I recommend you use FreeNX/OpenNX, it's way smoother and doesn't require you run the VM in level 5.

Re: X on CentOS instance
how much memory have you dedicated to the VM? I'd also start poking around in the logs for X see if there are any clear pointers to why X doesnt start.

That should be plenty, what's happening in the Xorg.log files?

Re: X on CentOS instance
looks like this is your issue: (EE) open /dev/fb0: No such device The guest cant find the frame buffer device. You should be able to google that up and hopefully find some solutions.

This happens to me whenever I do an installation of centos or redhat with CloudStack. I use the same iso on another hypervisor not managed by CloudStack and works ok I tested another iso and install new instances (RedHat and CentOS / with graphicall enviorement) and the result it's the same :( -- Hollman Eduardo Enciso R. http://nexxuz.com http://algolibre.com @hollman
Re: X on CentOS instance
Hi, this is due to PV mode VMs on XenServer not having a virtual graphics card. The console for such VMs is a serial console so X cannot run. If you need a GUI, try configuring VNC in the VM and connect directly using a VNC client.

The same iso with the same OS type (other (64 bits)) but in the installation menu i chose install system with basic video driver and work Ok. the X starts without problem. That's the only way to X starts ??? why this problem doesn't occur on XenServer directly? thanks to all -- Hollman Eduardo Enciso R. http://nexxuz.com http://algolibre.com @hollman
Re: X on CentOS instance
It should work as long as it doesn't require a virtual graphics card in the VM.

Re: X on CentOS instance
Using the Other OS Type is a solution since it will install the VM in HVM mode rather than PV mode. A VM in HVM mode has more emulated hardware, including a virtual video card so X can work, but with Linux VMs there will be other limitations (mainly related to performance). This exact same problem happens on XenServer with Linux VMs when using the correct template, but XenCenter tries to hide it. VNC will be installed and configured in the VM and XenCenter will connect to it instead of the serial console for the VM at the hypervisor level.
