Xen Orchestra 3.8

Release often, release faster: that's our motto this year. And we spent some time do give you a smoother experience when upgrading, with those objectives: Avoid appliance re-download for each new version Avoid any manual data migration on your side Ability to rollback to a previous release if anything goes wrong TL;DR again? Download it now! XOA updater Those previous requirements lead to those specifications: Include an updater in XOA Handle download of new Xen Orchestra versions Handle script migrations (e.g when the database structure changed) Handle updater self-update Handle rollbacks Not trivial eh? But we made it, and this tool is currently in last test phase. Basically, starting with the...

Add a network interface to a VM on XenServer with Xen Orchestra

The title is pretty much explanatory, isn't it? You'll see, that's very easy, in your VM view, you'll see it instantly, just click on "Create Interface" button: After clicking on "Create Interface", you'll have to fill the form, e.g selecting the network, MAC address and MTU: And after clicking on "Create", you're done!

XO live charts for host view

The next-release will offer a better visualization for the RAM occupied, and also the number of vCPUs used on the total number of CPUs. Those charts are animated on load: Your browser does not support the video tag. But also they are changing in live, when your host memory or vCPUs usage is modified (in this example, during a live migration of a VM in this host): Your browser does not support the video tag. Next step? Live metrics for all your VMs: CPU load, memory, network and disk usage with nice charts!

iSCSI and Jumbo Frames

So, you either just setup iSCSI or are having performance issues with your current iSCSI device. Here are some pointers to ensure "networking" is not the limiting factor: 1. Are my packets even making it to the iSCSI target? Always check in XenCenter that your NICS responsible for storage are pointing to the correct target IPS. If they are, ensure you can ping these targets from within XenServer's command line: ping x.x.x.x If you cannot ping the target, that may be the issue. Use the 'route' command to show if XenServer has a device and target to hit on...
