Re: [Xen-users] [libvirt-users] (Xen + libvirt) Installing and workin with xen -4.2.1 and libvirt 1.1.2

[cooldharma06 <cooldharma06@xxxxxxxxx>]

hi,

i prepared my xen-4.2.1 document with this mail. kindly refer the below attachment.

i installed libvirt 1.1.1 like this it giving the following error:

./autogen.sh --system --with-xen=yes

make

/daemon/libvirtd -d

then i checked with the virsh ->version

virsh # version

error: failed to connect to the hypervisor

error: no valid connection

error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory

but virsh -version -> 1.1.1

and also libvirtd --version -> 1.1.1

how to solve the above error.

Small request i found the libvirt but its not active kindly make active that one. It will help the beginners.

regards,

cooldharma06

Seems your libxenlight.so is not linked properly.  xs_check_watch is
provided by libxenstore, which should be linked with libxenlight

# ldd /usr/lib64/libxenlight.so.4.3 | grep libxenstore
libxenstore.so.3.0 => /usr/lib64/libxenstore.so.3.0 (0x00007faa807a5000)

As Dario mentioned elsewhere in this thread, you need to tell how you
"installed" Xen 4.2.1 from source.  Perhaps it is not
configured/built/installed properly.

Regards,
Jim
