[libvirt] libvirt-1.0.2 qith lxc and /proc/meminfo

Hello there I'm using libvirt-1.0.2 to spawn off linux containers We currently have 2 very similar setups that run on fedora 16 and f18 respectively And I'm seeing one weird difference concerning /proc/meminfo While everything is fine on the fedora16 world, on the fedora18 side here is what the container sees bash-4.2# ls /proc ls: cannot access /proc/meminfo: Permission denied 1 257 bus devices fb irq kpagecount mdstat net schedstat swaps tty 10 377 cgroups diskstats filesystems kallsyms kpageflags meminfo pagetypeinfo scsi sys uptime 15 522 cmdline dma fs kcore latency_stats misc partitions self sysrq-trigger version 16 542 consoles dri interrupts key-users loadavg modules pidsu slabinfo sysvipc vmallocinfo 18 acpi cpuinfo driver iomem keys locks mounts procprotect softirqs timer_list vmstat 19 buddyinfo crypto execdomains ioports kmsg lxcsu mtrr sched_debug stat timer_stats zoneinfo bash-4.2# ls -l /proc | grep meminfo ls: cannot access /proc/meminfo: Permission denied -????????? ? ? ? ? ? meminfo bash-4.2# cat /proc/meminfo cat: /proc/meminfo: Permission denied ===== we rebuild libvirt-1.0.2 more or less as is modulo a few features that are turned off, our specfile can be found here http://git.onelab.eu/?p=libvirt.git;a=blob;f=libvirt.spec the most obvious difference between both builds lies in using fuse: --- # fuse is used to provide virtualized /proc for LXC %if 0%{?fedora} >= 17 || 0%{?rhel} >= 7 %define with_fuse 0%{!?_without_fuse:1} %endif --- I was wondering what exactly should be the requirements on the root context for running this properly In particular the fuse rpm was not pulled as part of the libvirt dependencies, which might be an omission ? Can I expect my problem to go away if I make sure fuse gets installed ? Otherwise where should I try to look to solve this issue ? many thanks in advance -- Thierry
