Q: When I execute "virsh list" or other virsh commands I get the following error:
virsh: /usr/lib/libvirt.so.0: version LIBVIRT_PRIVATE_XXX not found (required by virsh)
A: It seems that libvirt installation scripts do not manage correctly the links to libvirt libraries when, for example, you manually install a version of libvirt and later change it to a new one or you try to use the libvirt version distributed as package.
To solve that, check the version you are using:
Remove the old links:
cd /usr/lib rm libvirt-qemu.so libvirt-qemu.so.0 libvirt.so libvirt.so.0
Recreate the links to libraries (change '0.9.8' by the version number you are using):
ln -s libvirt-qemu.so.0.9.8 libvirt-qemu.so ln -s libvirt-qemu.so.0.9.8 libvirt-qemu.so.0 ln -s libvirt.so.0.9.8 libvirt.so ln -s libvirt.so.0.9.8 libvirt.so.0
stop libvirt-bin start libvirt-bin
Note: do not try 'restart libvirt-bin'. It does not work, at least in our case...
Q: When I try to create a virtual scenario I get the following error:
VNX::vmAPI_libvirt::defineVM (1172): error connecting to qemu:///system hypervisor. libvirt error code: 38, message: Failed to connect socket to '/var/run/libvirt/libvirt-sock': ...
A: Seems that libvirt is not running correctly. Check libvirt configuration and be sure it works before executing VNX. Try commands like:
virsh list virsh capabilities
to see if you get an error message that will guide you. Have a look at the previous question and to this document http://wiki.libvirt.org/page/Troubleshooting.
