1) Check disk space on HW.
2) What vzctl version do you use?
3) Which centos-5 template do you use, default of minimal?

Thanks Vilaliy, this issue was solved, I had wrong my sysctl settings.

I have other question:

I setting my vps following the openvz wiki and have a routing error,
all vps have like default routing "192.0.2.1", not the HN default
route or my default HN ethernet interface.

Then I can't have internet access from my vps.

I using vzctl version 3.0.18

This happen with all template that I use and too with  the "oficial"
centos4-minimal template.

Can anybody help me ? Excuse my english.

Roberto

Because I was testing xen in the same server before.

With this kernel can I have xen and openvz together ?

Problem: when we do ping 192.168.0.2 (router) from VE100(192.168.0.1) then 
router answers don't reach the VE100.

I checked your HN and there are results:

Host 192.168.0.2 has permanent arp entry for ip 192.168.0.1:  00:16:3e:72:36:5
Although arp entry for ip 192.168.0.1 (VE100) must be 00:18:F3:50:72:AC ( the 
same as for HN ip 192.168.0.5)

------------
Decision: you must delete arp entry for the host 192.168.0.1 on the host 
192.168.0.2.
