XenServer performance alerts

New year, new features in Xen Orchestra: "performance alerts". In short, you can decide which VMs or hosts you want to monitor, and XO will send you an email if some thresholds are reached. Let's see how it works! Note: this feature is completely independent of the existing

XCP-ng on tracks

MirageOS Winter 2017 hack retreat roundup

MirageOS Winter Hack Retreat, Marrakesh 2017 This winter, 33 people from around the world gathered in Marrakesh for a Mirage hack retreat. This is fast becoming a MirageOS tradition, and we're a little sad that it's over already!

Announcing the Availability of XenServer 7.3

We're pleased to announce the availability of XenServer 7.3, the latest Current Release (CR)! CRs Versus LTSRs XenServer 7.3 offers customers following the CR release track access to the latest product features designed to enhance application, desktop and server virtualization deployments.

As many of you will be aware, XenServer is available in three editions: Free, Standard, and Enterprise. All of them are installed from the same ISO, and all are equally open source. The Standard edition is almost identical to the Free edition in terms...

To be an encrypted ninja or not to be...

Its a debate whether or not foreign powers hacked into Hillary Clinton's private email servers. There is consensus however that the private email server was hacked though, and this is precisely how emails can easily get leaked. To solve this sort of problem you can either have Hilary and Hilary's friend's become ninjas at cryptography, have cryptography tools become mainstream and transparent, or have a middle ground solution somehow. For this year's 2017 Hackweek at SUSE and Aaron Swartz day I have worked on a middle ground solution as a proof of concept using GPG, forcing all incoming emails to...
