Hi, the first thing that comes to mind, did you set ip_forward to enable in /etc/sysctl.conf ? net.ipv4.ip_forward = 1 Should explain why you IP on the bridge works but not on the vms.

Yeah, I thought about that, and while it's not specifically

What is aggravating, though, is virtually every howto on bridging out there refers to the deprecated brctl utility (from the bridge-utils package), and C8 no longer includes that package (even though

Hi, I want to add 2 vlans by the following steps: 1. add the vlan interfaces: vconfig add eth0 100 --vlan100 vconfig add eth0 101 --vlan101 2. modify the network-bridge script by the websit, http://wiki.xensource.com/xenwiki/XenNetworking#head-04ebcc1760dbc4678e83b116afa310dc0612dc39 Comment each time ifup or ifdown commands are executed.The reason is that ifdown ends with

Hi Steffan, I run my VMs on c7 using qemu-kvm + libvirt + virt-manager and the same on a slackware 14.2 without any problem. What error/problem do you receive?

Hi all, I've several questions about C8. I'm using 8 on my personal NAS and works very well. I'm running several VMs with centos 8 and noticed something: 1) Why corosync, pacemaker and pcs are missing on C8? They are only available on rhel with payments( rhel ha addons)? 2) Why there is only Gnome as available DE? I use centos on my workstation and I'm a kde-plasma user. XFCE

I'm really curious how you were able to virtualize CentOS 8. What platform are you using? Xen, KVM or VMWare? PV or HVM? I started a thread here and was referred to a project page for development. There was a thread on the forums for this which I replied to but it's been dead too so when I saw your opening sentence I'm really interested in, how'd you do it? Thank you, Steffan

I have all my issues posted on the forum - https://centos.org/forums/viewtopic.php?f=54&t=71934 I'm using Xen and it seems to be an issue with pvgrub and grub2. No matter what I do, it always boots into the grubdom> prompt. I made the changes suggested in the thread but can't get past that. HVM is fine but slow. PV just won't work. Thank you, Steffan Cline steffan at
