similar to: Xen and Centos 6.5

Hello, we have a strange problem on a fresh install of CentOS 6.5. On the server we want to use Xen to host paravirtualised guests (the system has no hardware virtualization support). To manage the domain we would like to use libvirt. Xen and libvirt are set up as described here: http://wiki.centos.org/HowTos/Xen/Xen4QuickStart http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt When

I've got a Centos 5 server with Xen installed. I'm trying to install a Centos 6.5 VM on it but once all is installed, the X window will not sync or display. I think I understand that it's probably due to the settings on the vnc stuff. I've got Centos 6.2 VMs that act just fine. Is there a way I can modify the VM's screen settings either during installation or after

Hi, Actually, we study virtualization on CentOS with Xen, our goal is to test if the migration of Xen with SLES 11 to CentsOS. Our first tests are ok except for one problem and I don't find any solutions on the net. I hope, you can help me. The problem is that I can't connect to my vm desktop with Virt-Viewer. I follow the installation guide available for centos?:

Hi, I have a server with Supermicro X7DVL-3 (P9) motherboard, 16G ECC RAM and LSI SAS 1068e RAID controller. I installed CentOS 6.5 64bit on the machine without any problems, but after following the Xen setup steps at http://wiki.centos.org/HowTos/Xen/Xen4QuickStart which installed me the kernel 3.10.32-11.el6.centos.alt.x86_64, I encountered a problem: After "Starting certmonger

I had so much trouble putting Centos 6 guest VMs on a Centos 5 host that I finally switched to a Centos 6 host. I've not needed more that test VMs, so I've used Virtual Machine Manager on the old system, which worked pretty well, so I decided to create my first KVM guest machine. I noticed when I created it, I only had the options of NAT for my network interface, so I used that

In honor of Xen Doc Day, I've put up some basic HOWTOs for setting up bridging on CentOS 6 and 7. I'm far from an expert, so I'd appreciate any feedback. The howtos can be found here: https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Networking6 https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Networking7 -George

I'm going to have to be a little vague on this one, but hope I provide enough to make the question clear. I'm not doing the work on this server, a co-worker is, but I said I would ask for him. He is trying to get DRBD installed. He's using Centos 5.1 and the yum repos, but is getting problems with things like the kernel, drbd.so, and the likes. All install fine, but I'm not

Sorry for the extra info required, but I had digest mode turned on and wouldn't have received the mailing till tomorrow. I have since updated the data manually, but after 'yum update tzdata' was run, the zdump -v for EST5EDT and America/New_York all still showed a date of April 1, instead of March 11. After manually fixing, it is correct. This was mostly a question about why yum

Hello, I posted a question over at xenproject.org but it was recommended that I send out a message here for help. My post there: http://www.xenproject.org/help/questions-and-answers/vanilla-pv-centos-guest-via-kickstart-centos-6-6,-xen-4-4.html The TL;DR is: Everything I've found to kickstart a new vanilla rhel/centos guest points to specifying a kernel & and initrd- for RHEL/Centos 5.

Hi, after migrating to libvirt/libxl according to: https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt I've noticed that my Xen PV domains are being launched by qemu-system-i386 running under root privileges. I am wondering why is this? Previously no qemu process was used. If qemu is needed for some reason, are there any guidelines for non-root operation? Thanks -- Karel

I see the announcement from February that it's available, but is it considered to be safe for Production use? The documentation in the SIG still only references CentOS 6. https://wiki.centos.org/Manuals/ReleaseNotes/Xen4-01 https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

I've got a couple of Samba4 DCs running as VMs for testing. The primary AD DC went smoothly. The second VM joined properly and all but it's only when I get to the replication tests that I see errors. This is following the wiki When I run the command "samba-tool drs kcc -Uadministrator windowsdc.mycrap.cnpapers.dom" I get an error indicating that

I've built a new mail system with Centos 6.5, and I'm running fetchmail - sendmail - procmail to maildir. I have all of this working at the moment.(I know, postfix was the default, but for lots of other reasons, I switched, and that isn't an issue, I don't think). I am using dovecot as an imap server. Procmail won't update indexes during email delivery, so I'm having some

I read a few days back on the list where the tzdata rpm was to take care of the new DST rules. I run CentOS 3 servers, and did a 'yum update tzdata' , but received a 2006a update of the rpm. Is this proper? It sure didn't fix anything. Thanks Steve Campbell campbell at cnpapers.com Charleston Newspapers

I'm a little new to Samba when used as more than just a simple place to mount a single user to a single share, but we're now getting ready to replace our Netware servers with Samba, and I guess that means Active Directory DC. As I read more and more about this beast, I keep finding pages that indicate the samba4 rpms supplied with the Centos/RH distribution are not the full version

Hi all, I'm trying to install libvirt for xen on a brand new, minimal installation of CentOS 7.5.1804. After installing the OS, I did a 'yum update' and followed the basic how-tos at https://wiki.centos.org/HowTos/Xen/Xen4QuickStart and https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt From previous experience, I know that the above steps worked fine. However,

I'm still not seeing emails from the list. With help from others, I thought I had the IPs cleared since the change back in February, but apparently not. Can someone PM me and let me know what outgoing IP addresses the list is using please? steve campbell

I just installed Centos 5.5 with the xen kernel on an older machine. It has Xeon processors and a 700 Mhz processor speed, so I realize I must use para-virtualized guests. Reading the Centos/RH Virtualization Guide gives examples of the process of installing guest hosts, but it only lists installing Windows as a fully-virtualized host. Is that because they only showed those types of examples

I have a raid 50 array on a 3ware controller. The box is running centos 6.5 and the file system is ext4. I'm going to try some other filesystems, but could anyone suggest any alternative raid setups as well as stripe sizes I should try? The old server uses the same controller on a centos 5.10 setup, using ext3, and it performs much faster i/o. The old 3ware setup is raid 5. -chuck --
