1320344273 M * Bertl wifigeek: hello
1320344539 M * wifigeek Bertl - not quite sure I follow how COW works on vserver
1320344549 M * wifigeek had a look at http://linux-vserver.org/Vunify
1320344584 M * wifigeek Can I create multiple VM's which are based on a single source? or do I need to create the VM first then use unify?
1320344610 M * wifigeek by based on a single source, I mean each VM just contains pointers to a master copy, unless it differs
1320344630 M * daniel_hozac -m clone will create it by linking the files that can be linked.
1320344650 M * wifigeek ah.
1320344667 M * wifigeek next question is, has anyone ever done a test to see how many vservers they can run on one box? :-)
1320344677 M * wifigeek I would be looking for thousands, each with <15M memory footprint
1320344705 M * Bertl we stopped at roughly 10k guests with a single task
1320344720 M * wifigeek not bad
1320344731 M * Bertl (because that comes near the process limits on an average system)
1320344748 M * wifigeek yeah, I would probably be increasing the kernel process limit to cope with my insane idea.
1320344754 M * Bertl note that we did those tests quite some time ago on relatively 'old' systems
1320344760 M * wifigeek yeah
1320344788 M * wifigeek I have been doing my tests with openvz, but the main problem I find is io. extracting each guest individually just eats my disks
1320344800 M * wifigeek and each guest is 99% identical
1320344806 M * Bertl so I'd expect a 32 CPU system with 64GB memory to handle quite a lot more
1320344810 M * wifigeek yeah
1320344851 M * Bertl there is something similar, but not so smart in Virtuozzo(tm) IIRC
1320344867 M * wifigeek yeah I want something free as cost is a factor here (as always!)
1320344869 M * Bertl i.e. in the commercial 'branch' of OVZ
1320344893 M * wifigeek vserver looks like a better fit, as I will be doing exactly as your test above. i.e. one process per container (or near enough)
1320344910 M * wifigeek especially if I can avoid lots of disk space using links
1320344963 M * wifigeek its likely I will have to write an API/wrappers for vserver to do what I want in terms of creation of guests etc
1320344990 M * wifigeek know of anything like that which already exists? i.e. API for creation of guests. I have had a quick google
1320345038 M * daniel_hozac the vserver ... build command?
1320345095 M * wifigeek looks close enough to what I need
1320345103 M * daniel_hozac if you want more than that it entirely depends on what you want to achieve.
1320345122 M * wifigeek yeah, I will probably just wrap up the vserver commands in an API interface for my webapp to speak to
1320345147 M * wifigeek last question (I promise!) - on the host node, I assume I can see the processes running for each container from ps aux?
1320345166 M * wifigeek its been many years since I looked at vserver, went to openvz a long time ago
1320345168 M * daniel_hozac PlanetLab's NodeManager is able to manage guests, if you live in their ecosystem.
1320345173 M * Bertl from the spectator context, yes
1320345188 M * wifigeek ok
1320345194 M * wifigeek sounds like I will give it a whirl :-)
1320345337 M * wifigeek The box I am testing on in question can scale up to 256GB ram, 24 cores and has at least one SSD (for testing)
1320345353 M * wifigeek so I will provide some feedback on the number of VM's I can run before it falls over.
1320345393 J * chrissbx ~chrissbx@69-196-180-202.dsl.teksavvy.com
1320345403 M * Bertl wifigeek: great!
1320345423 M * Bertl btw, it is advantageous to build guests without init
1320345441 M * Bertl i.e. you can save the resources for the init process if it isn't needed
1320345451 M * wifigeek aah
1320345452 M * Bertl (and usually it isn't :)
1320345460 M * wifigeek I did consider that, just wasnt sure how feasable it was :)
1320345472 M * chrissbx Hello. Is it normal that vserver-stat does not keep a total of userTIME and sysTIME for guests? (When processes exit, their times are subtracted from the total again.)
1320345477 M * wifigeek I need mono as part of my guests, but im sure I can do without init
1320345565 M * wifigeek bbl -> hometime.
1320345902 M * daniel_hozac chrissbx: what kernel and util-vserver versions?
1320346176 M * chrissbx 3.0.7-vs2.3.1+ (not sure why +, I don't think I've applied any changes myself), util-vserver git 5c59135 (+ my patches, the ones I already showed you once, https://github.com/pflanze/util-vserver)
1320346179 M * Bertl off for a powernap .. bbl
1320346185 N * Bertl Bertl_zZ
1320346206 M * chrissbx s/the ones/those/
1320346354 M * daniel_hozac are you not using cgroups?
1320346398 M * chrissbx hm, is this in the kernel or vserver config?
1320346415 M * chrissbx Kernel config has CONFIG_CGROUPS=y
1320346461 M * daniel_hozac what does cat /dev/cgroup/<guest>/cpuacct.stat show?
1320346503 M * chrissbx From the host? There are no <guest> subdirs there.
1320346547 M * chrissbx BTW kernel is 64 bit, host is 32 bit userspace, guest is 64 bit userspace.
1320346564 M * daniel_hozac so you're not using cgroups then...
1320346568 M * daniel_hozac that'll be why.
1320346582 M * daniel_hozac it's resorting to basically suming up your processes.
1320346597 M * chrissbx Aha, why does the userspace bit width matter?
1320346608 M * daniel_hozac it doesn't.
1320346613 M * daniel_hozac at all
1320346633 M * chrissbx Aha, you mean, the why is that there are no <guest> subdirs.
1320346651 M * chrissbx So I guess I'll have to enable this in the vserver config.
1320346686 M * daniel_hozac it should be automatic on your kernel, assuming you have the memory controller enabled.
1320346696 M * daniel_hozac (which is needed for accurate memory readings)
1320346744 Q * hparker Quit: Quit
1320346747 M * chrissbx What's the memory controller? A kernel config? Maybe a module? (I've got tons of modules, because I went from a Debian kernel config)
1320346788 M * daniel_hozac CONFIG_CGROUP_MEM_RES_CTLR
1320346834 M * chrissbx I don't have that (not even commented out); going make menuconfig.

1320347793 M * chrissbx tn:/etc/vservers/build64# vserver build64 start
1320347793 M * chrissbx secure-mount: chdir("/usr/src/KERNEL"): No such file or directory
1320347826 M * daniel_hozac does it exist?
1320347832 M * chrissbx When I do have this dir: chris@build64:~$ l /usr/src/KERNEL
1320347833 M * chrissbx total 0
1320347848 M * chrissbx Aha wait,
1320347856 M * chrissbx I mount /usr afterwards, duh.
1320347905 M * chrissbx hm. still doesn't work;
1320347925 M * chrissbx I guess the /usr/src is not visible in the context where the mount runs?
1320347976 M * daniel_hozac i'd have to see your fstab to really guess anything.
1320348096 M * chrissbx Duh, I bind mount /usr/src, later on, too. :~O
1320348102 M * chrissbx Sorry for the noise.
1320348260 M * chrissbx (If that was my subconscious wishing that fstab entries were automatically sorted, please excuse it. Of course I'm already telling it that since normal mount doesn't sort either, there's not much point to it. And that maybe symlinks are the reason for that.)
1320348559 M * chrissbx BTW /etc/mtab doesn't reflect what's mounted (seems vserver start doesn't update it); is the recommended practice to replace it with a symlink to /proc/mounts ?
1320348691 M * daniel_hozac /etc/mtab in the guest does get updated.
1320348800 M * chrissbx Huh, true, aha, it's just that df ignores entries with source directories that are not in the guest.
1320348830 M * chrissbx Whereas /proc/mtab uses /dev/sdaX etc instead of source directories for the bind mounts, which makes df show the entries.
1320348864 M * chrissbx Aha, df -a shows them all.
1320348898 M * chrissbx Stupid details :-I
