Issue
Static XEN compute resources do not work after OnApp install or upgrade to version 5.2-5.10.
Environment
OnApp version - 5.2-5.10
CentOS 7.x Xen 4.6 compute resources
Resolution
This can be normally resolved by excluding libvirt packages from CentOS-Base repositories before the update. To disable libvirt related packages from CentOS-Base repositories, do the following:
1. Edit the repository config file:
/etc/yum.repos.d/CentOS-Base.repo
2. Correct the exclude statement for the [base] [updates] [extras] repositories:
exclude=ntfs-3g ntfsprogs libvirt* perl-Sys-Virt*
Cause
Red Hat dropped XEN support from its Red Hat Enterprise Linux distribution and so releases libvirt packages without the support. As a result, libvirt packages are not compatible with XEN compute resources.
