Dear experts,
I am trying to install a Qlustar OS on several Ethernet-linked machines and still compute nodes do not boot. The installer reports that there have been no errors, head and FE VM nodes do start, Qluman sees them and I could not find any error messages from dmesg except insignificant note that firmware load for regulatory.db failed. I installed a Debian system on one of compute nodes and upon configuring the network interface with a static address, established an ssh connection both with the head and VM-FE nodes. At least this ensures that cables are OK. If I configure it as dhcp, it does not discover dhcp server. If I force BIOS boot from the network, I receive either PXE-E51: No DHCP or proxyDHCP offers were received from Intel Boot Agent, if I make BIOS use only Legacy OpROM, or Media Present ... Start PXE Boot over IPv4 ... with a silent subsequent fall back into BIOS Setup, if I choose to use UEFI driver. I tried different combinations of Boot Device Control {UEFI_and_Legacy_OpROM|UEFI_only|Legacy_OpROM_only}, Boot from Network Devices {Legacy_OpROM_first|UEFI_driver_first}, OS TYPE {Other_OS|Windows_UEFI_mode} in BIOS Setup, and none of them worked. Qluman confirms that Boot network is configured as dhcp, and systemctl says that there are no failed services.
Since I am the only one on the forum with such a problem, probably it can be fixed easily. However, I have no idea what to check and look forward for help.
Thanks, Alexei
