[Xen-devel] CentOS PV DomU freezing while booting

["Srujan D. Kotikela" <ksrujandas@xxxxxxxxx>]

Hi,

I have created a CentOS DomU on CentOS Dom0 (xen 3.4.3) using xen-tools and the following command:

> xen-create-image --hostname=TestDomU --ip=192.168.122.2 --dir=/xen --dist=centos-5 --install-method=rinse --gateway=192.168.122.1 --netmask=255.255.255.0 --mirror=mirror.centos.org/centos/5.5/os/x86_64
Then I started booting the system using the following command

[root@mgomathi-lab2 das]# xm create /etc/xen/TestDomU.cfg -c
Using config file "/etc/xen/TestDomU.cfg".
Started domain TestDomU (id=1)

  ----------------> FREEZES <--------------------

The DomU freezes and the shell becomes unresponsive after this.
