10:12 < mjungwirth_> hi rxr
10:13 < rxr> heyho
10:13 < mjungwirth_> have you seen my last message (at 21:20)
10:15 < rxr> mc-mp might be a generic e2fs lib incomaptibility, API change, nto optimization
10:15 < rxr> needs to be fixed indeed, need to check taglib

11:14 < Baldzius> moin
11:15 < rxr> hi Baldzius
11:15 < Baldzius> moin rxr
11:15 < rxr> Baldzius: for the vm, how much cpu power do yo need for it to be useful ?
11:16 < Baldzius> I don't really know, whatever suits you
11:16 < rxr> 2 cores, 3 cores, ...?
11:16 < rxr> I mean a rough number, like faster what you have
11:16 < Baldzius> 2 cores should be fine I'd say
11:16 < rxr> or that it is always on, ...
11:17 < Baldzius> always on?
11:17 < rxr> compared to your laptop
11:17 < rxr> just to have some number from where it starts to be useful
11:17 < Baldzius> well my laptop builds pretty fast
11:17 < rxr> to scale the other VMs down and plug in your former openvz container
11:17 < Baldzius> but it was fine as it was
11:18 < rxr> you mean the VM was fine ?
11:18 < Baldzius> yeah
11:18 < rxr> yeah, you got 7 cores I think
11:18 < Baldzius> only I/O was little dodgy
11:18 < rxr> though KVM eats too much performance on this stupid Intel Xeon ...
11:18 < rxr> (gotta get some AMD massive-core, ...)
11:18 < Baldzius> cpu wise?
11:18 < rxr> yeah, Intel VT sucks ...
11:18 < Baldzius> lovely
11:18 < rxr> anyway, the problem was that it was inside a openvz container
11:19 < rxr> like freebsd jail or solaris container
11:19 < rxr> and this "monster linux kernel patch" that openvz is was hightly instable
11:19 < rxr> and that while I was even using their last official, totally outdated 2.6.18 patch
11:19 < rxr> so I had to take the last openvz container (yours :-) down
11:19 < Baldzius> oh yeah, that's fine
11:20 < rxr> and I can not give you that much CPU back as bare KVM partition, as is's not as flexible as the old more softer scaling container was
11:20 < rxr> unless I ton this stpuid Xeon, and get some cheaper, more poweful AMD Opterons, Phenoms, whatever
11:20 < rxr> which I should probably do in any case, sigh
11:21 < Baldzius> as I said, everything will suit me
11:21 < rxr> maybe I should even start some cloud server company :-)
11:21 < rxr> yeah, but I want to make it useful for you, so, ...
11:21 < Baldzius> well then I need to test it first to give any feedback
11:21 < rxr> ok will setup in the next days
11:21 < Baldzius> but in general I don't think I will complian much
11:22 < rxr> we can flex scale, even migrate then anway, way esier than the former openvz junk
11:22 < rxr> IO thruput sucked indeed
11:22 < rxr> if that remains to be a bottleneck I should think about a better IO virtualization and RAID setup
11:22 < Baldzius> reading stuff around seems IO suck for KVM too
11:22 < Baldzius> sucks*
11:22 < rxr> as I said, maybe i shoudl start some cloud service :-)
11:23 < rxr> well, the soft raid 5 as the base might not be the most performant setup to start with, ...
11:23 < rxr> btw. I actaully use the more performant virtio backend (in stead of IDE of SCSI emulation, ...)
11:25 < Baldzius> but it's not comming with kvm, 3rd party no?
11:25 < rxr> comes with kvm
11:25 < rxr> sine many versions
11:25 < rxr> but you need OS drivers (included in linux)
11:26 < Baldzius> ic
11:26 < rxr> e.g. you can not juset boot /install some olde Win 2k or old Linux with virtio
11:26 < rxr> maybe virtio still sucks, is suboptimal
11:26 < rxr> at least faster than IDE emulation :-)
11:29 < Baldzius> I am planning to play a little with kvm and xen after my studies done
11:29 < Baldzius> 2 evenings was fighting to get lates xen-tools to compile
11:29 < Baldzius> and still can't get it xompiled
11:30 < Baldzius> got stuck with nasty linking problem
11:30 < rxr> do you use xen=?
11:30 < Baldzius> after they implemented bz2/lzma
11:30 < Baldzius> no
11:30 < Baldzius> would like to try
11:30 < rxr> I have the feeling xen is ading out, most betting on kvm
11:31 < Baldzius> yeah, many thanks to Intel I can't use kvm on this laptop
11:32 < rxr> usually it's possible to hack / tweak / edit the BIOS, NVRAM to enable it
11:32 < rxr> which model?
11:32 < Baldzius> Intel(R) Core(TM)2 Duo CPU T5670 @ 1.80GHz
11:32 < Baldzius> no vt support according to wiki
11:32 < rxr> really?
11:33 < Baldzius> I trust wiki :)
11:33 < rxr> grep vmx /proc/cpuinfo
11:33 < Baldzius> and I am not going to tweak it as it's not my laptop
11:34 < Baldzius> I checked that the first day I got it
11:34 < Baldzius> blank
11:34 < rxr> hm
11:34 < Baldzius> I knew that there are no vt before it was bought
11:34 < rxr> I thought all core 2 duo have it
11:34 < Baldzius> no
11:34 < rxr> lol
11:34 < Baldzius> even new released cpus don't have it
11:34 < Baldzius> that's why I don't like Intel
11:35 < Baldzius> for doing this
11:35 < rxr> http://rene.rebe.name/2009-01-15/intel-atom-no-64-bit-nor-vt/
11:36 < Baldzius> it's a mess across it's all dektop and laptop cpu models
11:36 < Baldzius> very very stupid
11:36 < rxr> yeah
11:37 < rxr> still need to hack enable VT on the Nokia Booklet with Z series Atom which theoretically has VT
11:37 < rxr> but disabled by BIOS as so often for Z Atom BIOSs
11:38 < Baldzius> I am waiting for the day when amd introduces something good and cheap for netbooks
11:38 < rxr> Neo
11:38 < Baldzius> very limited availability
11:38 < Baldzius> only hp (compaq) has it
11:38 < rxr> http://rene.rebe.name/2009-08-16/my-quest-for-a-usable-ntbk-continues/
11:38 < Baldzius> at least here
11:38 < rxr> Wind U210 U230
11:39 < rxr> maybe some new Lenovo laptop
11:39 < rxr> http://www.engadget.com/2009/11/18/lenovos-thinkpad-x100e-gets-detailed-amd-neo-based-not-a-netb/
11:39 < rxr> acer ferrari one
11:40 < rxr> it's pure vendors not getting devices out
11:40 < Baldzius> expensive
11:40 -!- digitaloktay [n=arch@dslb-088-064-175-147.pools.arcor-ip.net] has joined #t2
11:40 < rxr> probably all payed (getting extra discoun) by Intel
11:41 < rxr> Baldzius: the wind u210 (when soon or so shipping) should not be too expensive
11:42 < Baldzius> but it still has to come out?
11:42 < rxr> it's shipping in some countries for some time
11:42 < rxr> france or so
11:42 < rxr> maybe US / canada
11:42 < rxr> not in Germany
11:43 < Baldzius> I need to check it's availability in uk
11:43 < Baldzius> haven't noticed it yet
11:43 < Baldzius> and actually never heard of it
11:44 < Baldzius> it slipped through my eyes
11:59 < Baldzius> only u100 is available
12:03 < rxr> yeah, companies are strange
12:03 < rxr> not shipping the only barely usable products where people are waiting, ...
13:40 < mjungwirth_> rxr have you checked the taglib?
13:41 < rxr> you mean update it's cache file?=
13:43 < mjungwirth_> yes update for cmake
13:43 < rxr> Committed revision 34914.
13:44 < mjungwirth_> thanks
13:44 < Baldzius> we need to update cache files before heading for 8.0-branch
13:44 < mjungwirth_> is 8.0 released ?
13:49 < Baldzius> not yet
13:49 < mjungwirth_> is a release date defined ?
13:54 < Baldzius> it's very hard to stick with the plans
13:54 < Baldzius> originaly we were talking about october and today is november
13:54 < mjungwirth_> :)
13:55 < Baldzius> we could branch it today but it would involve massive merging I believe
13:55 < Baldzius> and it's time consuming
13:56 < Baldzius> maybe after my studies I'll have more free time
13:56 < Baldzius> exam should be in 3-4 weeks
13:56 < mjungwirth_> much luck for the exam
14:00 < rxr> some kind of sponsor for fulltime work would certainly help, like Google, Palm, etc.
14:00 < rxr> Baldzius: I have -rc2 builds mostly ready
14:00 < rxr> I hope the gcc-4.4 built kernels actually boot :-)
14:01 < rxr> though 2 problems anyway, silo on sparc64 and linux26 on ppc (IIRC)
14:01 < rxr> need to investigate
14:01 < rxr> want to tag -rc2 ASAP, hopefully also these days, like this weekend
14:01 < Baldzius> related with gcc update?
14:01 < rxr> yes, both issues should be due gcc-4.4
14:01 < rxr> ppc64, x86 and x86-64 did built, however
14:01 < rxr> only linux26 ppc and silo on sparc
14:02 < Baldzius> ic
14:02 < rxr> that is this are minimal builds
14:02 < Baldzius> I will test x86-64 when it comes out
14:02 < rxr> but during testing I'll emerge a lot, like xorg-server
14:02 < rxr> so those other packages will get some gcc-4.4 testing incl. run-time as well
14:09 < Baldzius> I need to set system for the laptop I got back from my sis
14:09 < Baldzius> so will also test some run-time bits
