Initially, I just rebooted from LiveCD and left Grub,kernel and dracut do
their job with the defaults, but unfortunately, boot process stops at

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

kickstart: dracut-initqueue fails due to unresolvable hostname even though network config looks perfectly ok
This problem still bites us. I've tried to play around with DHCP
settings (rd.net.timeout.dhcp, rd.net.dhcp.retry) to no avail.
I'm happy about /any/ hint.
Cheers

kickstart: dracut-initqueue fails due to unresolvable hostname even though network config looks perfectly ok
Hi,
kickstarting fails due to problems with host resolution, even though the
network seems to be properly configured through DHCP. eno1 and eno2 are
both attached to the network, but only eno1 gets an IP via DHCP. Still
`curl` cannot resolve the mirror host and the kickstart host during
dracut-initqueue:

At this point, I'd start wondering about the grub2 defaults, and the
kernel command line.

Aparently dracut does not want to activate the LVs required to boot to the
root filesystem, for some reason ...

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
Finally, I was able to find a solution for this. I'm posting the result
here, just in case that it's useful for someone else in the future ...
The problem was not in initramfs (dracut), but on the fact that /dev/sda2
partition(PV), after I resized it, somehow got 2 partition table
signatures.
One was set as a "dos" partition with an offset "0x1fe" and second set as

Trying to set-up DomU CentOS 7, but get Warning: /dev/root does not exist
I'm trying to set-up a ContOS 7 DomU server. I have used the PXE set-up images like I normally would for earlier versions of CentOS.
Here is my config file:-
name = "centos7"
memory = 2048
disk = ['phy:/dev/xen6/centos7,xvda,w' ]
vif = [ 'mac=xx:xx:xx:xx:xx:xx' ]

KVM won't boot after update to 1804
Hi Everyone,
I have a server that I recently applied all updates to to bring it to
1804. After rebooting the server, it would no longer boot and is
instead dropping into a dracut shell. Here's a snippet of the output
printed to the console (lines will likely wrap):

migrated RHEL7/CentsOS7 VMs fail to boot
I migrated a CentOS7 VM (the fedrtc.org site) from an XCP environment to
a libvirt/KVM environment.
This involved using qemu-img to convert the image from VHD to qcow2 and
then using virt-install --import to define the VM in libvirt.
Three problems occurred during boot:
a) on the first boot, the BIOS screen and grub screen don't appear at
all, the screen is blank for a couple of seconds and

Yes, basically that option was not there by default, I added it during the
troubleshootig steps. Normally, rd.lvm.lv=centos/root and rd.lvm.lv=centos/swap
are the kernel parameters which are parsed to dracut for enablig the two
LVs, but somehow dracut does not.

rd.lvm.lv on CentOS Stream 9 (first-boot failure)
I've install a CentOS Stream 9 system from a kickstart file that
specified (among other things) several logical volumes:

As far as I can tell, this is because in the dracut boot process, the
device backing VolGroup is activated, but the device backing BackupGroup
is not.? As a

4.9 kernel fails to boot because it didn't have the mpt3sas module
Howdy,
I hit a snag trying to install Xen4CentOS on a Supermicro based system
(X9DRD-7LN4F with the Broadcom/LSI 2308 chipset). I spent a few hours on
this today, I'm posting this here in case it helps anyone else and saves
them the frustration I dealt with.
On this system I did a fresh install of CentOS 7, updated it, rebooted it,
then installed Xen.
