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.

Hi CentOS users, I have install CentOS 7 in VirtualBox, and want the guest CentOS using dynamic IP address (The network type is bridged). I find the guest CentOS can works OK when using ethernet cable, but can't get IP address via wireless network. I also posted this issue on stackoverflow

This problem still bites us. I've tried to play around with DHCP settings (rd.net.timeout.dhcp, rd.net.dhcp.retry) to no avail. I'm happy about /any/ hint.

Hi, kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP. Still `curl` cannot resolve the mirror host and the kickstart host during dracut-initqueue: rdsosreport.txt ------------------------------------------------ [...] [ 14.780428]

During the build (via a serial console) we get input: ImExPS/2 Generic Explorer Mouse as /class/input/input1 running install... running /sbin/loader Sending request for IP information for eth0...

I have a KVM setup. Host is 6.3. I have a bridged client running 5.9 Since upgrading to 5.9 I noticed that ntpd is being restarted every 12 hours.

Dear All, I'm trying to configure wireless card on a Dell Vostro 1540. I had a look at this site : http://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom?action=show wireless card :# /sbin/lspci | grep Broadcom 12:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) I decided to follow the ELrepo instructions suggested on the site :

Hi everyone, We seem to be having issues on multiple CentOS 7.3 machines. The problem seems to revolve around polkitd. At some random time, polkitd seems to stop responding on my systems. Along with this, there might be hundreds of defunct pkla-check-authorization processes. If I reboot, then things are fine for a while. I don't see any activity in the unabridged journal to suggest anything

I'm trying to setup an external journal device, but it won't mount as ext3. I can only mount it as ext2. Everything seems happy when I run the commands. It will work when I don't use the external device. This is on RH7.2, linux-2.4.18-rc2. [root@dhcp4 root]# mke2fs -O journal_dev /dev/hdb5 [root@dhcp4 root]# mke2fs -j -J device=/dev/hdb5 /dev/hdb6 [root@dhcp4 root]# mount -t ext3

Hallo, thanks but this doesn t work here allthough most tips and hints are using this parameter. Any idea how to debug ?

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome. Thanks in advance Patrick Here after is an extract from the log July 1st 2016,

Well? I?m not convinced KEA can?t be simple DHCP, though I understand that one would never know that from reading the KEA documentation. The following is a complete KEA configuration suitable to do a single subnet. In fact, you could probably get away with slightly less. I?ve replaced the unique addresses from my environment with placeholders (e.g. <network/mask>), but otherwise, this is a
