When converting CentOS 7 OpenVZ systems to KVM sometimes there is no login prompt after loading services. The machine is otherwise operating correctly.

Rebuilding the initial ramdisk will fix that: dracut -f
Quick fix… Rebuild the ramdisk. If you are using a rescue disk and are compiling for a different kernel version replace $(uname -r) with your kernel version: dracut –mdadmconf –fstab –add=”mdraid” –filesystems “xfs ext4 ext3 tempts devotes syses proc” –add-drivers=”raid1″ –force /boot/initramfs-$(uname -r) $(uname -r) Add the following to /etc/default/grub inside the quotes for the […]

Ubuntu doesn’t seem to process MTU path discovery the same as other operating systems. When receiving a packet larger than the MTU it stops processing at the MTU length and then determines the packet to be too short as it doesn’t match the packet header. A quick resolution to this is to lower the MTU […]
