Re: Your laptop experience with CentOS

CentOS has worked well on laptops for me once it has working drivers. My last 2 systems had issues with drivers until some of the point release updates added them. The previous system did not have working wifi drivers. My current system (Asus UX303U) would not work properly with the video card. In e...

Re: luks and lvm

First, I apologize for resurrecting such an old thread. The LUKS over LVM vs LVM over LUKS issue has just cropped back up for me. I just wanted to share and document how I performed a LVM over LUKS install rather than the default LUKS over LVM in CentOS 7. **** DISCLAIMER: I prefer LVM over LUKS. If...

luks and lvm

I recently moved to CentOS 7 from CentOS 6. I noticed that the default drive encryption moved from lvm over luks to luks over lvm. The difference can be seen via the lsblk command where C6 would have sda 8:0 0 931.5G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 930.5G 0 part └─luks-{long-string}...

KVM bridge NIC DHCP Fails no IOMMU

This is intended to be more of a knowledge share as I didn't find the specific solution recommendation via google. This is a rather simple solution that seems to be working well. I have a CentOS 6 box as a KVM host. I have as one of my VMs, a system that is my firewall. There are 2 physical NICs on ...

Re: Virus Scan via Thumb Drive

We have began using rescue CDs such as F-Secure Rescue CD, Kaspersky Rescue Disk, etc. I thin Avast has one also. These are bootable linux based systems that require network connection so that they can go out to the internet to get the updated files. We have them incorporated into a rescue USB that ...

Re: CentOS 6.5 + Samba 4.1.6 - Variable Substitution (smb.co

We create home directories via pam upon user connection. We use winbind for authentication, but it shouldn't matter for you. To have winbind make your home folders for you automatically, add the following line just before the “session” criteria section in /etc/pam.d/system-auth : session required pa...

Re: KVM problems

This may be barking up the wrong tree, but make sure that you are using VirtIO for your disks and NICs. When I first installed KVM, there was a CPU virtualization feature disabled in the host system BIOS. That prevented me from using VirtIO. Once I enabled that, I was able to install as VirtIO and t...

[RESOLVED] NFS poor performance (and that is putting it mild

There are a number of guides for tuning NFS on the internet. Googling "tune nfs" will find many guides. The link you used is using the sync option in /etc/exports. That will slow nfs dramatically. Try using (rw,async,no_root_squash) in /etc/exports and mouting with -fstype=nfs,rw,noatime,nodiratime,...
