Centos5

[John Wick]

Hi,

One of our client still use this OS. Their application is huge and they not plan to upgrade OS. Is it possible on proxmox? Please advice.

Thanks.

Yes. Using CentOS5 in a VM is possible on PVE.

Regards,

HDD not available when choose SCSI.

Install choose VirtIO, success install. But after reboot, not detect hdd. Any idea why? I saw some thread said installation centos5 on proxmox still not fix.

I suggest you use SATA for CentOS 5.

Generally you should use virtio-scsi on Linux, but this driver is only included in 6.3 and later.

For what it is worth, moving the client to something slightly newer than CentOS5 should be ~more or less straightforward and ~painless. My vague recollection is that moving services over from a CentOS 5.X box to a 6.X box is not really a big deal. At least not as much change as when compared to going to CentOS 7.X (ie, core services like MySQL, Apache, etc - will all be ~similar enough that your old config won't need a 'major version rebuild tweak' to bring anything over).

centOS5 is getting rather long in the tooth these days anyhow, so making a gentle argument that a 'transplant to newer OS' is a good thing (ie, from security / patching / general sanity perspective)

I believe that CentOS 6.X will run quite painlessly as a KVM guest on Proxmox (ie, with proper VirtIO support, etc) and no drama.

You really don't want to use Centos 5.x now ... support for this has ended 31th of March 2017

I'll throw in a vote for CentOS 6.9 too.

It is so much better than CentOS 5.

 

[remark]

I have CentOS 5.9 (Elastix 2.5 distribution) KVM VM on Proxmox 4.4, it runs just fine.
Disk device and 3 network devices are VirtIO.
