[Qemu-devel] Help for backport virtio to older kernel 2.6.18

Hi All,

 

It seems that virtio disk driver is included in kernel version started from 2.6.32, but for 2.6.18 (using redhat5 as VM), we have to
backport  the virtio  driver. And I found that there is a link in link below, but cannot be opened.  Could you provide help on it?
Thanks!

*	Backport and instructions can be found in  <http://www.kernel.org/pub/scm/virt/kvm/kvm-guest-drivers-linux.git>
kvm-guest-drivers-linux.git

 

 

 

 

 

Best Regards

Halsey Pian

Red Hat Enterprise Linux 5 guests support virtio devices.  You should
not need to compile or backport anything for virtio-net or virtio-blk.

Please refer to the official documentation and support channels:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/index.html

Stefan,  Redhat 5 does support virtio block, but for other Linux distributions with kernel < 2.6.25 no virtio support, we also need
backport virtio if we want to use it. 
I checked the link for backport it in KVM website, still cannot be found. Would you have some info for it? Thanks!

The kernels you are looking at are very old.  I'm afraid I don't have
the information.  You will have to search around yourself and maybe
check git.kernel.org for old repos.

However, I suggest you get in touch with the distros you are using.
Maybe they have already done the work of backporting virtio drivers.
