AW: AW: Run Windows on top of KVM+virtio? Watch out for Windows updates, system unbootable!

2015-12-10 Thread Jochim, Ingo
Nux, I worked with the SUSE VMDP drivers (downloaded from SUSE) on Xen quite a lot in the past. Upgrading the drivers was always a nightmare and we ran into bluescreens very often. Since version 2 they also come with Virtio. I don't know if those are the same drivers which come with Windows. An

Hi Patrick, Connecting multiple remote access vpn clients from behind nat (from the same public ip) is not supported in strongswan vpn also. I think this is possible with the ikve2 but not with ikve1. Ikev2 i have not tried. Thanks, Jayapal On Mon, Oct 26, 2015 at 5:11 PM, Patrick W. wrote: >

I too use NetScaler and I actually found compression to have more of an impact than caching. Caching probably didn't help as much due to the jQuery stuff. On Dec 10, 2015 8:30 PM, "Nux!" wrote: > Hi, > > I've been running something like this without issues using mr Kinsella's > instructions for a

Hi, I've been running something like this without issues using mr Kinsella's instructions for a good while now. http://theresnomon.co/2014/improving-cloudstack-ui-performance/ I've seen visible improvements in performance, at least with the version we have in production (4.4). HTH Lucian -- S

Ingo, Yes, I use the same. But the drivers "SUSE Storage/Net" in Windows Optional updates override them. Verified on 2008r2 and 2012r2. Luckily the damage is limited as they are in the Optional channel, not sure how many people chose to install those alongside the Important ones, but hopefully

The fact you didn't find all the references in database is OK - XenServer can "spawn" extra files by itself and rename new UUID-s to old ones in order to keep VHD UUIDs consistent. This is also described in an article I have sent you before. I would only trust the output of "vhd-util". It seem

Hi, you can use the virtio drivers from the Fedora Project. I didn't have problems on W2k12 and W2k12R2. https://fedoraproject.org/wiki/Windows_Virtio_Drivers Regards, Ingo -Ursprüngliche Nachricht- Von: Nux! [mailto:n...@li.nux.ro] Gesendet: Mittwoch, 9. Dezember 2015 10:42 An: dev C

Hi Giles, We use Netscaler to accelerate ACS, albeit only static content as Erik mentioned. It is only really beneficial with multiple ACS Management Servers (and ours are 1 hop away @ 2Gbps). And to re-iterate what Erik said, the browser will cache most of the content. Kind Regards, Timothy

Vladim, thank you again for follow up. The references below, found or not found are to CS MySql database. All the files are actually there, they are LV devices in CLVM, I just did not find any references in CS database for their UUIDs. The corrupt one is: /dev/VG_XenStorage-3b6e386d-8736-6b6b-70

Re: cloudstack UI through accelerator/cache/proxy

2015-12-10 Thread Erik Weber
The only thing you could cache as far as I can see is static content (js, css, pictures) and list calls. Anything that triggers an action has to reach the mgmt server and cannot be cached. When caching list calls you have to either have a really short lifespan, or a proper method of invalidating t

I’m trying to get a basic understanding on how much the performance of the ACS UI would improve if it was run through some form of accelerator/reverse proxy/cache (i.e. something like a netscaler) Scenario is a management server that is a long way (physically) from the users, therefore latenc
