[Xen-users] xen 4.5-unstable, oxenstored cannot start (centos 7, kernel 3.17.0)

[ÐÑÐÐÐÑÐÐ ÐÑÐÑÐÐ <grigory.ptashko@xxxxxxxxx>]

Hello.

I'm running CentOS 7 with mainline kernel 3.17 built by myself.

I've configured the kernel with all the xen parameters as

builtin instead of modules. Yesterday I've decided to try to

build and install Xen from sources. I've pulled the latest

sources from git, changed the branch to staging and built

and installed xen like this:

make xen

make tools

make stubdom

sudo make install-xen

sudo make install-tools

sudo make install-stubdom

Xen installed and I got xen-4.5-unstable.gz in the /boot.

I have to say that I'm using PXE boot to boot CentOS. Bridged

networking and nfs rootfs works great thanks to Dracut.

I booted xen with PXE boot. It was not a problem.

xl dmesg shows usual xen boot log.

But. The oxenstored is not starting.

Simple sudo xl list just hangs. I looked at the

/var/log/messages and found there some bad looking messages.

I don't know if they are connected somehow but here they

are:

1. xenstored.service and xenconsoled.service

What can cause these problems? I don't understand yet where to dig..
