Summary: Deployed a new Turbonomic OVA 5.8.3 for some testing.  Logged into appliance via console, ran 'ipsetup' as instructed w/ 'static' selected.  VM stayed online for about 5 min. before dying. Workaround: Assuming DHCP is not an option, you simply need to change the 'bootpromo' entry from 'static' to 'none'  in the /etc/sysconfig/network-scripts/ifcfg-eth0 configuration file. You may also need to kill the dhcp client via killing network manager systemctl stop NetworkManager chkconfig NetworkManager off "NetworkManager" is case sensitive systemctl restart network OR You can utilize nmtui to modify system eth0 configuration. If issues persist, utilize above steps. Details: At some point it was likely that Turbonomic upgraded their OS instance, but failed to take into account a change in the OS' option 'static' being no longer a valid value and has been replaced w/ 'none'.  Seems to...

Summary: Attempting to troubleshoot IP and port connectivity issues on a Turbonomic appliance is a bit difficult.  The target configuration 'target status' doesn't really give enough information and the default toolset in the appliance ssh session doesn't provide telnet, traceroute, or netcat.  As long as your appliance has internet access, you can install these tools fairly easily though. Details: Quite simply, assuming nothing changes later, the appliance runs OpenSuSE.  You can make use of zypper to install the additional tools needed such as netcat, telnet, and traceroute: zypper install netcat-openbsd Usage of netcat is the same as ESXi which you can reference here  or use 'man netcat'. Installation of telnet and traceroute are a bit more straightforward: zypper install telnet zypper install traceroute Notes: These tools simply give you an idea of connectivity from the appliance's perspective. Traceroute can help you determine if anyt...

I was lucky enough to attend the inaugural Nutanix .NEXT conference in Miami the last 3 days.  I learned a lot and met many new faces.  Here is the bottom line: Nutanix has released their flavor of the KVM hypervisor dubbed " Acropolis ". So what does that mean for you VMware shops? Right now, possibly lower or complete removal of hypervisor licensing costs.  However, VMware is a leader for a reason, so you will likely need to augment by using something like VMTurbo to manage and give you smarter DRS like capability plus more.  I'll need to read-up on Acropolis feature sets, but the fair comparisons would likely be between the base vSphere ESXi editions (including vCenter)  vs Acropolis / Prism  and/or the vCloud Suite vs. Acropolis / Prism / VMTurbo combo.  It's going to come down to features and price. I'm thinking personally that it "MIGHT" be cheaper to go an Acropolis / Prism / VMTurbo route strictly from a licensing perspecti...
