Re: [Xen-users] xen server install on Fedora 21

[Colin Durrant <colin@xxxxxxxxxxxxxxx>]

So I discovered that for some reason I had Redhat kernel-xen-release-6-5.noarch.rpm installed so have removed it.

I have run this command successfully

yum -y install xen xen-hypervisor xen-libs xen-runtime

However, still have the original issues where the Xen modules are not running.

root@xenserver1 ~]# systemctl status xenstored

Hi

 

I am having a challenge trying to get Xen installed and working on Fedora 21.

 

I have installed it but the xen modules are not in /etc/init.d/

 

I get the following errors:

 

 

running this command - xl info

Gives me:

xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
libxl: error: libxl.c:92:libxl_ctx_alloc: cannot open libxc handle: No such file or directory
cannot init xl context

 

 

 

 

If I run this command:
systemctl status xenstored.service

I get:

● xenstored.service - Xenstored - daemon managing xenstore file system

           ConditionPathExists=/proc/xen was not met

 

 

 

running this -  systemctl status xenconsoled

 

Gives me

 

● xenconsoled.service - Xenconsoled - handles logging from guest consoles and hypervisor

           ConditionPathExists=/proc/xen was not met

 

Appreciate some help please?
