Cannot SSH into the self hosted host (going through tutorial)
Hello. I want to install oVirt on my PC and for this purpose I'm following the tutorial which instructed me to make a VM and install there the oVirt self hosted host: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine... I cannot SSH to this new oVirt install - I get the error "Connection refused" (Even though I see something listening on port 22 by running `netstat -an`). So I tried stopping `sshd`and I got the same error. Tried to do all of this with `telnet 192.168.122.1 22`, I get the same error "Connection refused". Also, Yum returns "could not resolve host: https://mirrors.fedoraproject.org" I can ping the machine though from my PC. I turned off `firewalld`. `iproute -S` returns `ACCEPT` for everything. My PC is running archlinux and I installed the new VM using "Virtual Machine Manager". Normally, I can easily SSH to any VM I create. Maybe someone know what I'm doing wrong? Thanks kindly Jenia P.S. Running `nodectl check` returns "ok" for all.
I cannot ping, cannot ssh, cannot telnet to the self hosted host. I don't understand why. I want to be able to SSH to to somehow for example. Can someone please give a hint?
PING works actually. I disabled all iptalbes rules: iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I killed firewalld I can see sshd listening on 22 netstat -anp | grep 22 tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1086/sshd Here is a screen shot: https://photos.app.goo.gl/XhM9Zd8yEq5S5QAUA I don't understand why my Ovirt VM is unreachable. Can someone please give a tiny help?/ P.S. Ping works!! So there's a route: https://photos.app.goo.gl/nSL39U9vejYPHwcS9

It's a bit hard to understand what exactly you are trying to do. Did you read a bit about oVirt and understand its architecture? What hosted-engine is? You probably need to disable MAC filtering on your host. No idea how to do that in "Virtual Machine Manager". You have: 1. Your physical machine/host 2. A VM inside it acting as an oVirt host, with its MAC address (assigned by the virt software on the host) 3. A vm inside that one, so-called the hosted-engine VM, with its own MAC address (assigned by the hosted-engine deployment process). When (3.) tries to access (1.) (either directly, or the outside world through it), (1.) sees the traffic on the vnic of (2.), but with a MAC address different from (2.)'s. So it might block it. That's just a guess - I don't know archlinux's "Virtual Machine Manager". If you are doing this for studying, and do not have a spare physical machine for doing the hosted-engine install on, it might be better to first try standalone (non-hosted-engine) setup. It will be more work, and require you to learn more, but will hopefully be easier to understand and debug if something goes wrong. Good luck and best regards, -- Didi
