Recovering From a vCenter Failure
While, in my opinion VMware’s vSphere is the best performing and most stable hypervisor available, vCenter obstinately remains a single point of failure when using vSphere and it’s no different when leveraging vCenter in a CloudStack environment. Therefore, very occasionally there is a requirement to rebuild a vCentre server which was previously running in your […]
CloudStack European User Group – March 2016 | Event Roundup
The spring meetup on March 3 saw us back at the BT Centre Showcase here in London, and it was an impressive turnout, maybe helped by a beautiful, sunny day. This was a truly European user group, with people joining us from Germany, the Netherlands, Switzerland, and from as far afield in the UK as […]
Taxi for Citrix, now time for CloudStack to shine
Today, Citrix announced that it was selling off two product lines: Citrix CloudPlatform and Citrix CloudPortal. For once, many Cloud commentators are right: this absolutely IS Citrix picking up its ball and going home. They’ve thrown this business line over the fence to Accelerite from Persistent Systems. However the sale tells us more about Citrix […]
CloudStack 4.7 Metrics View | CloudStack Feature Deep Dive
CloudStack 4.7 (which is due in the coming weeks) will introduce a new metrics view feature throughout the familiar CloudStack interface. We built this functionality to help system architects and admins comprehend resource utilisation and drill into the data to find performance hotspots. Whilst metrics have always been available via the CloudStack API a lot of information hasn’t been […]
Recovery of VMs to new CloudStack instance
We recently came across a very unusual issue where a client had a major security breach on their network. As well as lots of other damage their CloudStack infrastructure was maliciously damaged beyond recovery. Luckily the hackers hadn’t manage to damage the backend XenServer hypervisors so they were quite happily still running user VMs and Virtual Routers, […]
CloudStack European User Group – November 2015 | Event Roundup
An intimate feel at yesterday’s European User Group only seemed to encourage discussion, and despite slightly lower numbers than usual we managed to run a little late! Hosted by our friends at Trend Micro here in London, we started with lunch, and once everyone had eaten it was down to business. Giles Sirett (chairman of […]
System VM Upgrades
Recently we’ve seen a few clients being tripped up by the System VM upgrades during the CloudStack upgrades in multi-zone deployments. The issue occurs when the System VM is pre-deployed individually to multiple zones, rather than being a single template deployed to multiple zones. This may be done in error or because the specific version […]
CloudStack European User Group – May 2015 | Roundup
For the Spring meeting of the CloudStack EU User group on Thursday, we were again kindly hosted by BT – and it was nice to see so many of the BT Cloud guys come along to the group. As always Group Chairman Giles Sirett kicked things off with a roundup of Cloudstack news in the […]
CloudStack Primary Storage
Paul Angus, Cloud Architect at ShapeBlue takes an interesting look at how to separate Cloudstack’s management traffic from its primary storage traffic. I recently looked at physical networking in a CloudStack environment and alluded to the fact that you cannot separate primary storage traffic from management traffic from CloudStack, but that it is still possible. […]
CloudStack European User Group – February 2015 | Event Roundup
Once again, Trend Micro played host to the CloudStack European user group. And this quarter with Giles Sirett ‘working’ at CloudStack Day – Brazil, Geoff Higginbottom CTO of ShapeBlue took to the stage to compare the event. The News As is customary at the user group, we kicked off with a roundup of news in […]
