Hello,<br><br>Thanks again!<br><br>You mean that we should use for exemple this stable kernel : <a href="http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab044.11/vzkernel-2.6.32-042stab044.11.i686.rpm">http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab044.11/vzkernel-2.6.32-042stab044.11.i686.rpm</a> to get a lot of stability ? By following this little guide : <a href="http://wiki.openvz.org/Install_kernel_from_rpm_on_debian">http://wiki.openvz.org/Install_kernel_from_rpm_on_debian</a>.<br>
<br>The apps won't be so disk IO-vore. Tons of VM are for... LAMP / VocalServer / Minecraft & other game servers...<br><br>Another tips to have an OpenVZ Stable Node ?<br><br>I think we should use vzsplit -n 128 to get a UBC-configuration.<br>
I don't know anything else.<br><br>We've 12 dedicted servers on Debian 6. Some of them aren't so stable, using the kernel from repos. We sometimes need to make an hard-reboot.<br>We'll migrate these 12 servers to one.<br>
<br>Thanks !<br><br>PS: Sorry If I post wrong, first time use of mailing-lists.<br><br><div class="gmail_quote">2012/1/6 Kirill Korotaev <span dir="ltr"><<a href="mailto:dev@parallels.com">dev@parallels.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">>From RAM/CPU perspective this configuration is fine.<br>
But if you plan to run I/O intensive apps you may want to have more HDD drives (maybe with less capacity each) to make your raid capable to handle more IOPS.<br>
