Re: [CentOS] CentOS as Guest OS on Red Hat Virtualisation 4.x
You answered yourself basically, yes CentOS is essentially RHEL and it will run. Now, the article refers to "support" and that is different topic. It means that when you call Red Hat Support they will be able to help you with hypervisor if the guest does not operate properly. People often confuse phrase "is supported" with "does it run". Just make sure to select RHEL 7 guest configuration for CentOS 7 so proper drivers are in use for optimal performance. 2017-04-27 19:21 GMT+02:00 Ling Yew Kim : > Hi all, > > I have a banking customer asking if CentOS is compatible on RHV4.0 as a > guest VM.

Re: [CentOS] Anyone ever gotten Solaris to install from a CentOS PXE server?
Foreman does support Solaris out of box, I haven't tried this myself. It
runs in CentOS7.

Re: [CentOS] SELinux file permissions
Hello, restorecon works only for existing files, for new files you are looking for file transition rule. Google that out, there is plenty of articles on that topic, for example: https://fedoraproject.org/wiki/Features/SELinuxFileNameTransition LZ 2017-01-23 19:57 GMT+01:00 Tim Smith : > Hi, > > I'm trying to grant dovecot the ability to manage its socket within > the postfix spool directory. > > I have added the below to file_contexts.local : > > /var/spool/postfix/private/dovecot-auth system_u:system_r:dovecot_t:s0 > > > However, running "restorecon -v > /var/spool/postfix/private/dovecot-auth" gives me the following error > : > > restorecon: lstat(/var/spool/postfix/private/dovecot-auth) failed: > No such file or directory > > > I cannot create the socket file in advance, because dovecot manages > it, and if you "touch" the file, dovecot complains. > > Where am I going wrong ? > > Thanks ! > > Tim > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos > -- S pozdravem / Best regards Lukas Zapletal ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] CentOS iSCSI Install & Booting
If you do not want to use iPXE, an alternative approach is to have a USB stick (few hundred MBs is enough) for /boot partition. CentOS 7 installs just fine with this setup (/boot on local USB, the rest on iSCSI). This works better with kernel updates (can be more tricky with iPXE as you need to "synchronize" kernels and modules). LZ 2016-11-19 8:06 GMT+01:00 James A.
