Linux Virtualization

Edit grub on a VM on headless KVM Host


I Recently updated my OP5 machine later after an reboot got the error message.  Important to know is that i run my VM (Virtual Machine) on a headless server so i have no more tools then to VNC to a VM and therefore its hard to get into grub at boot as the timeout was set to 5 seconds.

Kernel panic - not syncing: VFS: Unable to mount root fs on unit block(0,0)
Network Virtualization

OpenMediaVault / Debian network configuration for bonding/lacp and vlan

This is an example of an network configuration on my OpenMediaVault server. It takes two network interfaces (eth3 and rename3) and bonds them together using LACP. On top off this bond i have created three bridges. br1 witch is for untagged traffic and. br641 and 642 for vlan tagged traffic on vlan 641 and 642 respectively. br1/br641/br642 are all attached to the host and is configured for dhcp. they can also be attached to virtual machines.
