difference between CPU server and client family
by jb 08 Dec '20

08 Dec '20

Hello, is there a big difference between *Secure Intel Skylake Server Family* CPUs and *Secure Intel Skylake Client Family* CPUs. I ask because I use a Intel Xeon E-2246G in our servers and when I install the cluster, the client cpu model was automatically selected. I'm not sure now if it makes a different, when I change the cluster cpu type to the server model and if this is possible with this cpu. Best regards Jonathan

what difference between enterprise Linux hosts and oVirt Nodes ?
by tommy 08 Dec '20

08 Dec '20

Enterprise Linux hosts (Enterprise Linux hosts) and oVirt Nodes (image-based hypervisors) are the two supported types of host. Hosts use Kernel-based Virtual Machine (KVM) technology and provide resources used to run virtual machines. But what difference between the Enterprise Linux Hosts and oVirt Nodes ? Please give me some explain in details,thanks!

strange dns request since 4.4.3
by Adam Xu 07 Dec '20

07 Dec '20

Hi ovirt Recently, my samba internal dns has been getting a lot of errors, like: [2020/12/02 15:24:31.484073, 1] ../../source4/dns_server/dns_query.c:1141(dns_server_process_query_got_auth) dns_server_process_query_got_auth: Failed to add SOA record: WERR_DNS_ERROR_RCODE_FORMAT_ERROR I found that my ovirt nodes was sending a lot of strange requests, I use tcpdump and got some like: tcpdump -i ovirtmgmt udp port 53 17:00:23.875038 IP ovirt1.adagene.cn.53862 > dc1.mydomain.com.domain: 35727+ [1au] NS? . (40) 17:00:24.436466 IP 192.168.49.195.domain > ovirt1.mydomain.com.33625: 8887 FormErr-$ 0/0/1 (40) about one request in a second. And I noticed that some nodes which version is 4.4.2 did't send dns requests like above. therefore no error occured. Were there any recent changes to ovirt node that caused these errors?

new hyperconverged setup
by dofranklin＠port-orange.org 06 Dec '20

06 Dec '20

I am about to setup a new hyperconverged setup with the following 3 host setup 2 x nvme 240gb hd for OS on each host (raid) 3 x nvme 7 tb hd for vm storage on each host (no raid card) 500gb RAM per each host I am confused during the gluster setup portion using the web ui setup wizard. When asked for the LV size do I input the maximum size of the hard drive on a single host or do I combine the total capacity of the matching hard drives on all 3 host? Example that I would be putting in is hard drive: /dev/nvme1p1 capacity 7tb or should it be 21tb (combined capacity of the matching single HD on the other host). Or is there a better method you recommend? And since I am using nvme hard drive would you recommend using dedup and compression or no? Thanks
