This is ludicrously biased and full of marketing-speak. I don't like XenServer much either, but for other reasons. It went open source because it's commoditized and they want synergy with XenCloudplatform (which you should use instead at any rate). The biggest wart about XenServer is XenCenter, but the Infrastructure Client is just as bad these days. And the screwy uuided LVM volumes. But on "performance" and "reliability" it's drat close to VMware and ahead on some benchmarks (performance is mostly irrelevant except in extremely tuned environments) You should use XCP instead of XenServer, but XenServer's feature set is miles ahead of Hyper-V and somewhat behind vmware. If you're too big for Essentials or Essentials Plus and too small for Enterprise, XCP or XenServer may be a great fit. E: I should say that XenServer is somewhat badly documented and has a fair amount of edge cases in large environments, but you probably won't run into them if licensing costs are an issue for your team evol262 fucked around with this message at 03:26 on Dec 27, 2013 |

Any thoughts on the "OS level" virtualization options like OpenVZ? My company currently rents a bunch of OpenVZ VPSes from a provider that we've been a bit unhappy with recently, and our use of them has expanded such that it seems like it might be worth looking in to coloing our own boxes. The use is Asterisk boxes where the customers only see a web control panel, but due to Asterisk's lovely multi-tenancy support we need each customer instance to think they have root on their own private machine. Only our staff ever sees the CLI, so the shared kernel and such aren't as big of a deal. All we need is a way to keep separate customers' Asterisk instances separate and allow guests previously on a failed box to be booted up elsewhere. Live migration is a huge plus, but not really a requirement. Is there a good reason to still choose a lower-level solution like KVM or Xen when every guest will be nearly identical? Are competitors like LXC mature enough to consider realistically?

LXC+SElinux offers more guarantees, but ring -1 virtualization will always be more secure. Additionally, running different kernel versions can have advantages. Admittedly, Asterisk is a finicky beast, and running identical kernels with patches can be a benefit. But yeah, LXC is stable and well-used.

Wicaeed posted:What was the reason you switched? I found it to be less reliable where the hypervisor itself would lock up every few months on random boxes. Very well could have been due to my coworkers lovely deployment. I wouldn't call it crap, but VMware is the industry leader for many reasons. We are also running a View environment, so I found it to make sense to have our servers run on the same hypervisor. For the price it is compelling, but it you have some money to spend, I much rather go with vSphere. How big is your environment and what kind of workloads are you looking to virtualize?

Posted about this over in SSD Thread as well, but wanted to see if anyone had heard anything new about forcing TRIM / garbage collection on ESXi SSD datastores? This sort of looks like you can use vmkfstools to force some kind of garbage collection?

I've heard of something like this but little to none of the deploys I have done have SSD in the hosts, or any storage for that matter aside from a 16Gb SD card. However, there is some nice use for SSD's in hosts for VDI. Might look into it. Dilbert As FUCK fucked around with this message at 05:36 on Dec 28, 2013 |

I'm also unsure what the state is of VAAI unmap -> TRIM. I just don't know whether it's an adapter/controller, or device firmware function that will associate the two together. If there is one, then sure, it'll work as hoped. Given that user's experience, it certainly looks like it, but I'm leery about saying it's going to work, or be the same experience across all TRIM-enabled disks. Edit: It's a roadmapped item and of interest. That much I can at say.

My domain is blah.thing.edu. Because blah is also the name of my department at the school of thing, it's the URL of our public website and other things. That means I can't have AD update the DNS a records for blah.thing.edu. So I manually made ad.blah.thing.edu with two A records pointing to my two domain controllers, which is what MS DNS does on its own with blah.thing.edu if you let it. So I put ad.blah.thing.edu as the auth server for VMware SSO, and today for reasons one of our domain controllers was down. While the DC was down vCenter was unable to authenticate. How is this "supposed" to be setup to authenticate against AD?

Bob Morales posted:Not sure if this is a SAN question or VMware question but I'll start here first. Usually you use FlexClone ($$$ license on the NetApp) to make a zero-space copy of the SnapMirrored volume, which is R/W and you can do all of your testing. Then you delete the FlexClone volume and it just goes away, leaving your pristine SnapMirror volume untouched the whole time. Without FlexClone, your options are more limited. You could make a new volume on the destination side, and then use a non-VMware tool (Linux - mount both volumes and copy) to copy VMs out of the SnapMirror volume and dump them into the dummy volume for testing.

The SRV records are all setup properly, it's just that one A record I had to manually create myself. As for the outage, it was since Saturday (which I just discovered today, lol monitoring). As for the actual error message, I didn't save it, but it said something about not being able to reach identity source.

I have all the SRV records in DNS properly. The domain itself functions fine, I just don't know what I'm supposed to be usingn to populate the server list for SSO. If I put in the IPs of the individual domain controllers, I can't every change the domain controllers, because as far as I can tell there's no way to change the servers for an identity source. If I use the A record for the domain, it won't work if one of the domain controllers is down, which ignores the whole point of having a hostname with multiple A records.

As an MSP, I'm pretty fond of SSO for our clients. But then, we didn't go through an upgrade to 5.1, we did a new install when we moved to it so we avoided most of the pain. We'll see how it goes when we upgrade to 5.5 this quarter.

I'm thing of reducing the ram our VCenter appliance has assigned from 8G to 4G as we only have two hosts and about 15 vms monitored by it.

I don't know about vCenter in particular, but it's never a good idea to tell Java that it can allocate more RAM than actually exists. Unless you want to get on the next train to Swap City.
