hi guys,
i'm about to host a site that pushes over 10mbps and i'm trying to host it inside proxmox.

i tested this briefly on a openvz container but it died with tcp_conntrack full dropping packets kernel messages.

so now, i'm thinking of installing it on a kvm, so i can control the kernel settings independently of the host.
but i want to confirm with you guys, if i setup a kvm VM, then i don't need to increase any sysctl settings on the debian host, correct?

btw, the server is intel romley, w/ 256gb memory, on raid-10 intel 520 ssd, so i'm pretty sure it's enough. he even said he been hosting it off single server so far, but he did have it on barebone and not virtualization.

right.
Do you use a bridged interface (veth) for the OpenVZ-container or venet?

for openvz, i use venet. for kvm, i use bridge.

currently i am now hosting the site on a kvm, currently have haproxy VM on kvm, and litespeed VM on kvm.
i've spread the traffic load across mine and his other hosting (2 apache servers).
the load average of host is at 3-5, and the load of both lb and litespeed are around 3-8.
cpu utilization is avg 10%, memory is below 3%, and disk io around 1% utilization.

when i try to take it all in my litespeed, response time starts to get slow, real slow.

but i know my server is quite capable of handling his entire load.
i wonder if this is due to KVM's performance limitation or if it is because there is some configuration tweak i need to make.

anyone have experience with hosting high traffic sites w/ proxmox? how was your experience like?

Hi Jae,
not for high traffic websites, but with an backup-server as OpenVZ-CT. Runs very well (many clients to spool-disk, and from spool-disk to two FC-LTO4 drives).
Runs nightly and we store round about 16TB each week. I used bridged network and don't reconised any trouble with that.
