[CentOS-virt] bridged kvm guest and ever changing MAC address
Hi, Centos 5.4, dual igb ethernet, kvm guest (Centos 5.4). br0 is connected to eth0, guest has virtio ethernet connected to br0. Guest is configured using virt-manager. When host is booting, br0 gets mac address of eth0. Every time i start guest (with virt-manager) vnet0 appears and br0 mac aadressi on host is changed. Why does it need to change the mac? I'd like to keep it same, not to change it every time guest is booting. -- Veiko ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

I had some DL160s with an old BIOS with no option for AHCI mode. After upgrading to the most recent BIOS, the option was there. Yes, there was an update, changelog described changes regarding to sata2 drives should work properly with this update. Did the update yesterday, but nothing changed except the bios version number.

Re: [CentOS] Centos 5.3, no AHCI on HP DL320 G5p?
Tony Mountifield wrote: That's probably why. To use AHCI you need to set it to RAID mode. Having done that, you can still use the drives independently if you prefer kernel RAID; you just have to go into the BIOS RAID setup and set the drives to JBOD mode (or something like that), by telling it to remove all RAID information from the drives. I don't think so, because I have another DL320 (older G3 version) with same bios setup (sata mode). On that G3, ahci is working. -- Veiko ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
