I have installed OpenVZ kernel on plain Ubuntu 16.04. When I tried to boot into the OpenVZ kernel (2.6.32-042stab116.2) I get the following error:

ERROR: Failed to mount API filesystems, freezing.

I have successfully booted into OpenVZ kernel on Ubuntu 14.04 but I'm facing issues with Ubuntu 16.04.

Could help me out as I need to compare performance of LXC and Openvz live migration on Ubuntu 16.04.

Your suggestion would be helpful to me.

Thanking you in anticipation.

Steps followed:

wget -P /etc/yum.repos.d/ https://download.openvz.org/openvz.repo

rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ

cd /tmp

wget https://download.openvz.org/kernel/branches/rhel6-2.6.32/042 stab116.2/vzkernel-2.6.32-042stab116.2.x86_64.rpm
wget https://download.openvz.org/kernel/branches/rhel6-2.6.32/042 stab116.2/vzkernel-devel-2.6.32-042stab116.2.x86_64.rpm
wget https://download.openvz.org/utils/vzctl/4.9/vzctl-4.9-1.x86_ 64.rpm
wget https://download.openvz.org/utils/vzctl/4.9/vzctl-core-4.9-1 .x86_64.rpm

wget https://download.openvz.org/utils/vzquota/3.1/vzquota-3.1-1. x86_64.rpm

apt-get install fakeroot alien libcgroup1

fakeroot alien --to-deb --scripts --keep-version vz*.rpm ploop*.rpm

dpkg -i vz*.deb ploop*.deb

selinuxenabled && echo enabled || echo disabled
echo "SELINUX=disabled" > /etc/sysconfig/selinux

Add following parameters to /etc/sysctl.conf file
# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled
net.ipv4.ip_forward = 1
net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.all.forwarding = 1
net.ipv4.conf.default.proxy_arp = 0

# Enables source route verification
net.ipv4.conf.all.rp_filter = 1

# Enables the magic-sysrq key
kernel.sysrq = 1

# We do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0

I doubt running the OpenVZ Legacy kernel on Ubuntu 16.04 will ever be supported or work.

For a comparison, I would use CentOS 6.x as the OpenVZ Legacy base distro... and then compare it to Ubuntu and LXC if you want.

But LXC live migration isn't supported in CentOS/RHEL.

It requires LXD package which is only available in ubuntu

Any update on this, I'm facing the same issue when trying to boot from OpenVZ kernel 042stab127.2 on Ubuntu 16.04. When searching for this issue, stumbled upon a link to a bug reported on Bugzilla https://bugzilla.openvz.org/show_bug.cgi?id=3280, but found out that they've moved to JIRA on https://bugs.openvz.org from Bugzilla, not able to find the related JIRA on https://bugs.openvz.org. If anybody has the link to that JIRA, please provide me that.
