Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
Hello, I'm having a strange problem booting a new centos7 installation. Below some background on this. [I have attached the tech details at the bottom of this message] I started a new CentOS7 installation on a VM, so far all good, o/s boots fine. Then I decided to increase VM disk size (initially was 10G) to 13G. Powered off the VM, increased the vhd via the hypervisor, booted from CentOS

Renaming virtio devices names on CentOS 8 VM guest
I have built a CentOS 8 base image from a kickstart, for use in OpenStack. This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>. I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have

I have a C7 server with a physical RS-232 console, but the config should be similar. I did not have to generate a systemd service for this; systemd saw the console line and automatically started the getty without me having to generate a

Serial Console Not Connecting to Dom0 on Ubuntu Server 12 Running Xen 4.1.3
Xen-users, I have what I think is a bug in the serial console interaction of Xen and Ubuntu. Essentially, the serial console appears to work just fine until it is passed off to dom 0 from Xen. Then it stops communicating with dom0, but still communicates with Xen, if I use the control-A escape sequence. Google will not show me anything related to this. I have local RS-232 serial console working

ubuntu 11.10, system V runlevel compatability
I''m having a problem with the boot sequence hanging indefinitely at "stopping system V runlevel compatibility". Here are the steps I took to get to this point: 1) installed a single boot, server version of ubuntu 11.10 (intended to be dom0) 2) apt-get install xen-hypervisor-4.1-amd64 xen-utils-4.1 xenwatch xen-tools xen-utils-common xenstore-utils 3) updated grub as follows: -

Garbled screen after RAM Scrub on boot
Dear All I am using Centos 7 with Xen 4.6 on a Dell Poweredge T430 When the machine boots, after the 'Scrubbing Free RAM' message, I get a screen filled with little white squares until the login prompt, so I cannot see what is happening as the machine boots. Also there is nothing on the screen when I reboot. My /etc/default/grub is GRUB_DISTRIBUTOR="$(sed 's, release

strange fencing behavior
I have 10 servers in a cluster running Debian Etch with 2.6.26-bpo.2 with a backport of ocfs2-tools-1.4.1-1 I'm using AoE to export the drives from a Debian Lenny server in the cluster. My problem is if I mount the ocfs2 partition on the server that is exporting it via AoE it fences the entire cluster. Looking at the logs exporting the ocfs2 partition doesn't give much information...

Renaming virtio devices names on CentOS 8 VM guest
Thanks Robert, I was doing that but it was still renaming to ens*. However, I now know why, and have fixed it. For those who are interested, the problem was that when I created the base image from a kickstart I didn't pass net.ifnames=0 to virt-create, and I ended up with an image that had forgotten about eth0 completely. I have now redone the kickstart with net.ifnames=0 and all is well.
