Keyboard backlight fails with recent kernels
by Rob Kampen 04 Oct '19

04 Oct '19

I do not use my laptop often, normally my better half has possession and use of it. It is a late 2011 ASUS ROG G73S which performs very well. The keyboard backlight was an issue initially under CentOS6, but the kind folks at elrepo found the missing bits in a more recent kernel and created a package to add them to the older CentOS6 kernel. An upgrade to CentOS7 went without a hitch and the keyboard lighting has worked fine. Recently I sat infront of the machine and couldn't see the keys - no backlight. A number of reboots later I have found that the latest kernel that I have on the machine, that works okay is 3.10.0-862.14.4.el7.x86_64 3.10.0-957.21.2.el7 and 3.10.0-957.27.2.el7 both fail to load/activate the driver for the keyboard. Would someone with the requisite knowledge please advise what I need to do. Is this a case for using the CentOSplus kernel or do I need to find and load a driver or two? or do I need to request the elrepo folk to make a suitable package. Thanks Rob

CentOS 8 as guest
by Jerry Geis 03 Oct '19

03 Oct '19

Hi all , I am running C7, and C8 as guest at this time. I noticed that when right click on desktop, and select display on C8 - that the largest resolution I get is 1080p, I am running a 4K monitor - is there a way to get higher resolution in the Guest. I am running with qemu 2.0.0 Thanks, Jerry

Upgrade from 7.6.1810 to 7.7.1908 -> Interfaces order not static
by Jobst Schmalenbach 03 Oct '19

03 Oct '19

Hi For years (long time) I had " net.ifnames=0 biosdevname=0 " and it worked as it should (6.X, 7.X) I never had any problems, until yesterday. I started upgrading my machines and I stopped after the first one showed issues and I will not update all the other ones until this is sorted. I have problems keeping the interfaces in order as I wanted them to be assigned to eth0, eth1 .. eth4 Every reboot the order of eth1, eth2 and eth3 change BUT eth0 stays. Now when I read this https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/ht… then I am doing the correct thing by adding the MAC as in so: DEVICE=eth0 IPADDR=... ... GATEWAY=... ONBOOT=yes BOOTPROTO=none USERCTL=no NOZEROCONF=true TYPE=Ethernet NM_CONTROLLED=no HWADDR=01:23:45:67:78:9a This works for eth0 but all the other ones the kernel complains /etc/sysconfig/network-scripts/ifup-eth: Device eth[1,2,3] has different MAC address than expected, ignoring NOTE: this worked until yesterday, I could reboot, update whatever it always came up in the same way and I also did not need to swap the network cables EVERY time ... Even without HWADDR/MAX adddress I have to swap the cables every time (eth[1,2,3]). Did something change in the kernel/networking/udev I am not aware of? What am I doing wrong all over sudden?

kernel-rt on CentOS 8
by Geoff Rosenberg 02 Oct '19

02 Oct '19

Hi, We have just upgraded to centos 8 at my lab, and are looking to install the kernel-rt. When we were on centos 7, we were tracking the repo at mirror.centos.org/centos-7/7/rt. However, there doesn't seem to be an rt directory for mirror.centos.org/centos-8/8. Is the realtime kernel housed in some other location for Centos 8? Thanks, Geoff

/boot partition too small
by KM 02 Oct '19

02 Oct '19

First off - let me say I am not an administrator. I need to know if there is an easy way to increase my /boot partition. When I installed CentOS 6 after running 5, it was my oversight not to increase the /boot size. it's too small and I can't do yum updates. if it's not easy to actually increase it, is it safe to take a chunk in my root filesystem (like /new.boot or something) and just mount it as /boot from now on so it uses the space or is that not a good idea? I am sure I could easily copy the rpms/kernel stuff over to it and then unmounts the real /boot and mount this new area as /boot. Can you administrators let me know what you think of all this? Thanks in advance. KM

Packages not in CentOS 8
by Jerry Geis 01 Oct '19

01 Oct '19

Hi all, I am using kickstart to install CentOS 8. Course I started with my kickstart from 7. Some packages are not found on the kickstart install (not present on the DVD I guess) like: ImageMagick sox libogg-devel libssh2-devel So again - I know they are not present on the DVD but they are present. What is the Kickstart trick to say %packages if not present - ATTEMPT to load later with yum ??? Is there such a thing for kickstart now with the new CentOS 8 structure ? Thanks, Jerry

Centos 8 and Lynx
by david 01 Oct '19

01 Oct '19

Folks I find the Lynx browser does not appear in any of the repositories used during default installation of Centos 8 (x86_64). Is this program no longer supported? I didn't see a reference to it in the notsupported list. David

CentOS-6 cannot get kvm guest to start - network error
by James B. Byrne 01 Oct '19

01 Oct '19

Need to start a virtual machine but missing nic is preventing this: I have need to recover some data from a guest on host which has been shutddown for some time. The host had one of it nic removed at some point. It is not likely to be replaced either. When I try to start the guest in question I get this: error: Failed to start domain inet09.harte-lyne.ca error: Cannot get interface MTU on 'br1': No such device I tried editing (virsh edit guest) to remove the interface: <interface type='bridge'> <mac address='52:54:00:35:a2:8a'/> <source bridge='br1'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </interface> I saved the changes and tried to start the guest. but I got the same error. Then edited the guest config to say: <interface type='network'> <mac address='52:54:00:35:a2:8a'/> <source network='default'/> <model type='virtio'/> </interface> How do I configure this guest so it will start without the missing nic? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
