...nfigurations. The incumbent system is a Xeon 8GB system running i686 CentOS 4.3 (what else?), with light CPU loading and very heavy IO loading (WD raptors are our friends). Folks with deep(er) knowledge of x86_64 architecture, I'd also be interested in the trade offs between 1CPU w/8GB and 2CPUs each with 4GB. (E.g. what's the real cost of shipping data back and forth between the memory spaces of the two CPUs? How does the 2.6 kernel deal with the split memory space? etc...) The memory is all going to be used up in kernel buffers keeping bits of files in kernel memory. Also, t...

I am using libvirt 1.2.20. I noticed that when running some VMs (CentOS ) with 2G ram, 2CPUs each for some reason they go from 'state=running' to 'state=paused'; and they can't be restarted. They are un-usable. When this happens I get the following in dmesg output: [ 46.595265] EPT: Misconfiguration. [ 46.595271] EPT: GPA: 0xfee000b0 [ 46.595275] ept_misconfig_i...

..._tables (kernel) AssignedTo: laforge@netfilter.org ReportedBy: gandalf@wlug.westbo.se CC: netfilter-buglog@lists.netfilter.org I'm not certain this is a SMP-race, it could be any other kind of memory corrupting thing... Inserting a rule on an quite active SMP (2cpus) router may give you some suprises it seems. Only seen once and I havn't tried to reproduce it yet since it's an important productionrouter but I'll test it on a testmachine. Ok so here we go, the router enables forwarding before any iptables stuff is activated (I should change the scr...
