CCing @bleader too. @sapcode said in openssl 1.1.1 update or manual build in XCP 8.2.1 possible ?: Would it be safe to run yum remove openssl as the first step or would this break the XCP installation: The second option. And actually it's not openssl you're looking for, it's openssl-libs, and removing it will not even work, as it attempts to remove yum and systemd which depend on it and are protected. Note that we do offer openssl 1.1.1 through the xs-openssl-libs package, and that is what XAPI uses for communication instead of the system one. However you'd have to patch and rebuild curl or wget so that they use it, and this definitely voids your warranty. You are going on a journey that is far more difficult than you initially expected, I fear. So I'd start questioning the initial needs again. Why do you need to contact websites such as ssl-tools.net from dom0? Can't you do it from a VM?

@sapcode Found a description here: https://linux.die.net/man/1/xm But no idea why it starts some CPUs in the pause state.... Will do some testing with C states and govenor performance.... STATES The State field lists 6 states for a Xen Domain, and which ones the current Domain is in. r - running      The domain is currently running on a CPU b - blocked     The domain is blocked, and not running or runnable. This can be caused because the domain is waiting on IO (a traditional wait state) or has gone to sleep because there was nothing else for it to do. p - paused       The domain has been paused, usually occurring through the administrator running xm pause. When in a paused state the domain will still consume allocated resources like memory, but will not be eligible for scheduling by the Xen hypervisor. s - shutdown   The guest has requested to be shutdown, rebooted or suspended, and the domain is in the process of being destroyed in response. c - crashed      The domain has crashed, which is always a violent ending. Usually this state can only occur if the domain has been configured not to restart on crash. See xmdomain.cfg for more info. d - dying         The domain is in process of dying, but hasn't completely shutdown or crashed.
