| 07:52 | <muppis> I know this is totally unrelated, but you've played with virtual machines as well. Ever tried (wonder was there a need at all) to run Windows XP Mode -virtual in Virtualbox?
| |
| 07:57 | Virtual itself runs fine, but it bargs about activation.
| |
| 07:58 | <highvoltage> Well, you need a full Windows license that lets you run it in a VM for it to work properly.
| |
| 08:01 | <muppis> It's same VM wich MS provides for Windows XP Mode in Windows 7.
| |
| 08:01 | Installation package provides Product ID.
| |
| 08:01 | <highvoltage> does its license allow you to run it outside of Windows 7?
| |
| 08:02 | <muppis> Propably not. :D

| 19:27 | <championofcyrodi> i have a really open ended question....
| |
| 19:27 | approx. how many LTSP Ubuntu FAT clients can I run on a core 2 duo w/ 8GB RAM?
| |
| 19:27 | basically, nbd, ssh, nfs...
| |
| 19:29 | <highvoltage> fat clients don't use much RAM or CPU, so short answer... a few dozen but it really depends more on your disk and network bandwidth
| |
| 19:29 | <championofcyrodi> a few dozen is currently more than enough...
| |
| 19:30 | 1Gbps..
| |
| 19:30 | sata II... ~300GB disk
| |
| 19:30 | i'm thinking the biggest hit will be NFS mounted home folders.
| |
| 19:30 | since nbd caches on client no?
| |
| 19:30 | <highvoltage> yeah that's where the disk bandwidth come in. 10 people start libreoffice at the same time and suddenly your disks effective bandwidth per user becomes 300KB/s.
| |
| 19:31 | <championofcyrodi> sounds good... most of my users will be running chrome, terminal, tmux and NX client.
| |
| 19:31 | and thunderbird
| |
| 19:32 | basically i have a docker container running ubuntu-ltsp on a severely over provisioned server with dual hex core, 128GB RAM, 2 SSDs, and more... wanting to use that server for something else.
| |
| 19:32 | so i'm just going to rsync /opt and /home... and commit the container to my registry... and pull it down to this weaker machine... then switch the TFTP host...
| |
| 19:32 | and i *think* that should do it?
| |
| 19:33 | i have tftpd + dhcp running elsewhere.

| 21:27 | <vmlintu> championofcyrodi: if you are using normal hard drives and are worried about hard drive performance, you can use dmcache with ssd cache for hdd+ssd combination on lvm partitions.
| |
| 21:27 | <championofcyrodi> vmlintu: sweet!
| |
| 21:33 | <vmlintu> championofcyrodi: here's some information about it: https://github.com/opinsys/dmcache-utils
| |
| 21:34 | <championofcyrodi> i heard the intel z97 mobos support ssd caching on top of hdd at the hardware level... to give you a logical drive w/ SSD cache.
| |
| 21:35 | havent tried it yet though. (don't have a z97 mobo) vmlintu:
| |
| 21:38 | <vmlintu> haven't heard about that
| |
| 21:39 | mostly I've been using dmcache in 2xhdd+ssd combination where hdd's are in raid-1 and ssd caches a single partition on raid-1 lvm volume
