First post to this list. I would appreciate some help on this issue. As background, I installed CentOS 7 on a Dell server, and then ran the following commands:
yum update http://buildlogs.centos.org/centos/7/virt/x86_64/xen/centos-release-xen-7-11.el7.x86_64.rpm yum --enablerepo=centos-virt-xen-testing update yum --enablerepo=centos-virt-xen-testing install xen Doing that, I was able to successfully install Xen, create a virtual machine with its own HVM setup, logical volume, etc. and boot it just fine. I then tried to do the same on an IBM x3550 server I’m trying to install with CentOS 7. The CentOS 7 install went just fine. I can boot into the standard kernel and have a working machine. But after running the commands above to install the Xen hypervisor, the machine hangs on boot for a few moments after displaying the lines below and then reboots in a loop over and over and over: Loading Xen 4.6.0-2.el7 … Loading Linux 3.18.21-16.el7.x86_64 … Loading initial ramdisk … It never gets beyond that. If I choose the stock kernel (no Xen) from the Grub menu, it will continue to boot into that just fine. My grub.cfg file has these entries of note: multiboot /xen-4.6.0-2.el7.gz placeholder dom0_mem=1024M,max:1024M cpuinfo com1=115200,8n1 console=com1,tty loglvl=all guest_loglvl=all ${xen_rm_opts} echo 'Loading Linux 3.18.21-16.el7.x86_64 ...' module /vmlinuz-3.18.21-16.el7.x86_64 placeholder root=UUID=9dc18146-f9b3-41cc-ba9c-7314689abcde ro crashkernel=auto debug irqpoll ipv6.disable=1 console=hvc0 earlyprintk=xen nomodeset echo 'Loading initial ramdisk ...' module --nounzip /initramfs-3.18.21-16.el7.x86_64.img What I have tried: 1) adding debug into the vmlinuz line 2) disabling ipv6 in that line 3) adding root=UUID=9dc18146-f9b3-41cc-ba9c-7314689abcde to the last line AFTER /initramfs …. Nothing so far has made any difference. Obviously the process works, as it works for me just fine on the Dell server. Underlying this machine is a SATA RAID 1 PCI card with two SSD drives attached in a RAID 1 mirror. Not that that should matter, but I’m including it for reference. As noted previously, it boots into the stock kernel just fine. Any help would be appreciated. -- Craig Thompson, President Caldwell Global Communications, Inc. 423-559-5465 ------------------------------------ This message has been scanned by WingNET for spam & virus content.
