similar to: Centos 8 server rebooting...

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

hi, I have configured a routed network on my laptop with a ipv6 subnet and dnsmasq is handing out ipv6 addresses to my vms and it works really wel, but finding out which ips have been used is not as easy as with ipv4.

I am having trouble with recovery. Today due to electrical work I powered down my networks Router / DHCP server. My Centos 7 host machines lost their DHCP lease (they are actually static leases). Once I power my Router / DHCP server back up none of my virtual machine were accessible. It appears that when the DHCP lease was lost on the virt server the bridge of the KVM guest were all losts. A

I did not hear back on this posting so I figured I was addressing the wrong audience. Maybe someone on the host-side better understands how the 4.12 kernel is interacting with KVM.

I''ve recently upgraded SLES to use LibXenLight and have noticed that my virtual machines no longer restart when "xl restart X" or the reboot commands are used within the VM. Instead the machine seems to get destroyed. The configs for the VMs have not changed since well before the update. Here is what one looks like: name = ''vm1'' maxmem =1024 memory = 1024

Greetings - I shutdown one of my Centos 6.2 VMs for some offline maintenance and am now unable to get it to restart. I am also unable to create and start a new VM. The host system is Centos 6.2, fully up to date. I have been searching Google for two days and have not been successful in getting a VM to start. I have restarted libvirtd, but did not want to shutdown my other two running VMs and

Hi All, Some more data on this, I've reproduced this on another host that's a completely stock centos/xen deployment with a centos 6.6 domU. Since I?m seeing the retransmissions on the VIF, I don't think it's related to the network stack but just in case.. Each host is connected via LACP with vlan tagging to a pair of stacked cisco 3750's. Host networking config is here:

Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com
