 Post subject: SSH Login to Vmware ESXi with ssh keys
PostPosted: Wed May 24, 2017 7:28 am 
To login with ssh private key in Vmware ESXi, store the public key in the following file: /etc/ssh/keys-root/authorized_keys
Code:
# cat mykey.pub >> /etc/ssh/keys-root/authorized_keys


Make sure to use double angle brackets to avoid losing the contents of /etc/ssh/keys-root/authorized_keys.

 Post subject: KVM Nested in Vmware ESXi 5.5 - enable guest hypervisor vmx/svm flags without vsphere web client
PostPosted: Sat Feb 21, 2015 8:21 pm 
Both Vmware ESXi and the open source alternative KVM (Kernel Virtualization Module) that turns a Linux server into a native hypervisor can run as nested hypervisors, meaning they are not installed on the bare metal machine, but they are themselves virtual machines under the other.

KVM nested in ESXi 5.5 - Requirements


In order for KVM module to load (or the packages to even install), the CPU has to have the Intel/AMD virtualization technology flags ...

 Post subject: ESXi: How to see network statistics for vSwitch port using esxcli
PostPosted: Mon Jan 26, 2015 7:07 am 
We are all familiar with Vmware ESXii vSwitches and how vSwitch ports are assigned to each machine individually. The vsphere client is a powerful tool for configuring vswitches, ports and VMs, but I prefer the black background and white font any day.

First step is to get the ID of the network port for the specific VM with esxtop command.

Identify vSwitch port ID using esxtop:


Run the "esxtop" command and press "n" key to ...

 Post subject: Vmware ESXi - esxtop output is not readable
PostPosted: Mon Jan 26, 2015 6:53 am 
"esxtop" command is similar to Linux "top" command and it shows system (cpu/network) utilization statistics.

Some vmware esxi deployments will show very strange output in "esxtop" command:e(PCPU 4)\%P-State P10","\\apophis\PCPU Power State(PCPU 4)\%P-State P11","\\apophis\PCPU Power State(PCPU 4)\%P-State P12","\\apophis\PCPU Power State(PCPU 4)\%P-State P13","\\apophis\PCPU Power State(PCPU 4)\%P-State P14","\\apophis\PCPU Power State(PCPU 4)\%P-State P15","\\apophis\PCPU Power State(PCPU 5)\%C-State C0","\\apophis\PCPU Power State(PCPU 5)\%C-State C1","\\apophis\PCPU Power State(PCPU 5)\%C-State C2","\\apophis\PCPU Power State(PCPU 5)\%C-State C3","\\apophis\PCPU Power State(PCPU 5)\%P-State P0","\\apophis\PCPU Power State(PCPU 5)\%P-State P1","\\apophis\PCPU Power State(PCPU ...

 Post subject: How to add BIOS boot delay for particular VM in VMWare ESXi 5.x
PostPosted: Wed Feb 19, 2014 4:05 pm 
Find the VMX file of the virtual machine and add the following line WHILE THE MACHINE IS TURNED OFF:
Code:
bios.bootdelay = 5000

The above line will add a 5seconds delay leaving enough time for bios related operations.

 Post subject: CentOS and KVM: Setup VNC server on the hypervisor
PostPosted: Tue Feb 04, 2014 9:05 am 
After a complete installation of the KVM hypervisor, libvirt and the rest of utilities, VNC server can be used to remotely access the graphical console (aka Video output) of the VMs via the Virtual Machine Manager.

But by default VNC will not run:
# chkconfig --list | grep vnc
vncserver 0:off 1:off 2:off 3:off 4:off 5:off 6:off
# chkconfig --levels 5 vncserver on
# chkconfig --list | grep vnc
vncserver 0:off 1:off 2:off 3:off 4:off ...

 Post subject: FreeBSD virsh console hangs in "Escape character is ^]" \w KVM hypervisor any text console provider
PostPosted: Fri Jan 31, 2014 5:35 am 
Installing FreeBSD under KVM requires a little tick to access the serial console (text) from KVM virsh because FreeBSD redirects output to video if using graphic installation (vidconsole).
Code:
# virsh console VM2
Connected to domain VM2
Escape character is ^]

After the box is installed and running configure the "comconsole" under /boot/loader.conf and configure the serial con
Code:
# cat /boot/loader.conf
console="comconsole"
# grep ttyu0 /etc/ttys
ttyu0   "/usr/libexec/getty std.9600"   vt100   on  secure
