similar to: how to add mount options for root filesystem inside lxc container

Hi all. Has someone success story with using autofs + nfs inside libvirt LXC container ? In my case nfs client and server in lxc work just fine, but with autofs hang on system call state(). I use CE7_64 on nodes and inside container with libvirt 1.2.18 May be I must set some of capabilities in <feature> (http://man7.org/linux/man-pages/man7/capabilities.7.html) ? I try only CAP_SYS_ADMIN

Hi. I need to use /dev/ppp inside the lxc container, for very ancient software.

Hello. Centos 7.6 with libvirt build from base "virt" repository: libvirt-daemon-driver-lxc-5.0.0-1.el7.x86_64 libvirt-client-5.0.0-1.el7.x86_64 libvirt-daemon-5.0.0-1.el7.x86_64 libvirt-daemon-driver-network-5.0.0-1.el7.x86_64 libvirt-libs-5.0.0-1.el7.x86_64 + systemd-219-62.el7_6.2.x86_64 Now lxc containers with type='direct' can be started, but can't be stopped :)

Hi all.

I decided that the next time I reformatted my main desktop computer (this one) I would have a ssd installed in it to use for the boot drive. Now that Centos 7 is on the horizon, I'm thinking that the time is approaching when I'll want to do that. The last time I set up a computer with a ssd in it, that was the only drive that it had. I changed issue_discards=0 to issue_discards=1 into
