Hi All - I use qemu on my centOS 7.7 box that has software raid of 2- SSD disks. I installed an nVME drive in the computer also. I tried to insall CentOS8 on it (the physical /dev/nvme0n1 with the -hda /dev/nvme0n1 as the disk. The process started installing but is really "slow" - I was expecting with the nvme device it would be much quicker. Is there something I am missing how to

Hello all, hope all is well/happy holidays Issues with an old thread out there, valid users containing an AD group Have tried this on systems running cent7u2 and ubuntu trusty. These systems are running sssd. I can login with AD users and chown/chgrp file with AD groups. However, I can't get AD groups to work with valid users for restricting share access. If I just set individual AD users,

I have been following the patches on nvme support on the list and was wondering: If I wanted to build a vm host to be on the bleeding edge for nvme and spdk fun in libvirt, which linux distro -- fedora/ubuntu/centos/etc -- should I pick?

Apologies if this has been gone over, but I believe I have checked the intertubes more than a bit..... I am using libvirt and have vms booting under an OVMF.fd to use an efi firmware. I can create vms, linux ubuntu, and they will boot up. However, everytime I reboot am I dropped into the default efi shell provide by the tianocore build. Then I must walk the FS to the booting efi app and run, in

Hi Rob & Mihai, I wrote vhost-nvme patches on top of Christoph's NVMe target. vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe driver. But the tests I have done didn't show competitive performance compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme vendor extension patches reduces greatly the number of MMIO writes. So I'd like to push it

hi guys, I thought I should ask before I start fiddling and break something - can we tell grub2 to add nvme device as an option to boot from? And if yes then what do tell grub? many thanks, L.

Thanks VERY MUCH for all the info and help! Apologies for the extreme delay. I got distracted by other threads that forced out this work to later date. Also some frustration as well. ;) I completely missed this update. Apologies and thanks Will be diving back into this shortly!

Thanks very much for the quick response/info sir Server is joined to the domain, which, I think, the info I listed demonstrates, apologies if not sssd has nothing to do with Samba. >>I somewhat understand that sir. I listed mainly to provide info on auth methods and services on the host. In case not listing affected diagnosis, and just in case samba did something different interacting on

Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file. Then I see the following message "kickstart install Started cancel waiting for multipath siblings for nvme0n1" This is what I have in the kickstart file # Clear the Master Boot Record zerombr #
