New guest tools ISO for Linux and FreeBSD. Can you help with the tests?

Pierre Briec

I've tried to modify the xe-linux-distribution file but i definitly don't have the skills to modify it. I don't understand the sed commands to identify
Can someone help me with that?

thanks in advance

@pierre-briec You may try this version of the script: https://raw.githubusercontent.com/xenserver/xe-guest-utilities/master/mk/xe-linux-distribution

@stormi
Thanks
Now, the OS seems to be detected
Here is the content of /var/cache/xe-linux-distribution

[root@ipfire-test ~]# cat /var/cache/xe-linux-distribution
os_distro="ipfire"
os_majorver="2"
os_minorver="unknown"
os_uname="5.10.55-ipfire"
os_name="IPFire 2.27 (x86_64) - core160"
[root@ipfire-test ~]#

I still don't know why xcp-center doesn't detect the agent management and if it would work as expected

I also change the xe-linux-distribution in /etc/init.d because the function action is not available in ipfire. I don't know what is the best way.
Is there anything to change?

thanks
Pierre

I think XCP-ng Center doesn't consider that the agent is working correctly if it doesn't report the IP address to the host.

Pierre Briec

@stormi

So i've made a mistake? the VM has an IPv4 address in local network but no gateway yet

stormi

I can't say whether there's an issue with the way you run the agent (xe-daemon) or in the agent itself. Maybe the way it collects the IP addresses is not compatible with how ipfire handles networking.

Pierre Briec

@stormi

yes, they are renaming the network interfaces (like red0, green0, blue0) and perhaps it's the problem.
So the agent should work as expected in PVHVM ? My previous VM it was only in PV.
thanks for your answer

stormi

Yes, the agent runs well in HVM VMs. Actually there are almost no reasons why you should use a PV VM nowadays.

Pierre Briec

@stormi
As Xcp-center reports that agent is not installed, i was afraid that it wouldn't work as expected.
I don't want to have low performances on that VM which will be the internet gateway.

stormi

Actually, on any recent enough Linux system (ie not many years old) , the PV drivers are directly included in the kernel. Unless, maybe, a very specific distro decides that they don't want Xen support in their kernel.

So the tools you install on the VMs are merely an agent to make the VM more cooperative with the hypervisor, but they don't affect performance.

The situation is different on Windows systems where you need to install PV drivers to achieve better performance.
