1. Proposed title of this feature request setup serial console for RHEVH 2. Who is the customer behind the request? Account: name (acct #) 5262884 TAM customer: No SRM customer: No Strategic: no 3. What is the nature and description of the request? Customer wants to setup serial console for RHEV-H. We can append serial console details to kernel line when RHEV-H is booting. --- console=ttyS1,57600n8 <== for example. --- But, customer wants to make persistant entry in grub.conf file. By-default, grub.conf file is in read-only mode. and to modify grub.conf we will need to remount it in rw mode. But, login to RHEVH shell with root access and making any modification is not supported by Red Hat. So, customer wants supported way to configure the same. We do have workaround: <snip> To modify the grub.conf, remount /dev/.initramfs/live in read-write mode as, it is symlink to /boot/grub/ --- # mount -o remount,rw /dev/.initramfs/live --- Then modify grub.conf file and append serial console parameters to kernel line. </snip> 4. Why does the customer need this? (List the business requirements here) We use Dell's serial over lan capability to remotely manage our systems. 5. How would the customer like to achieve this? (List the functional requirements here) Ability to append console=ttyS0,115200 to the kernel line in /etc/grub.conf in a supported fashion (through the Admin menu I'd guess). 6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented. 7. Is there already an existing RFE upstream or in Red Hat Bugzilla? No. 8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)? Sooner the better. 9. Is the sales team involved in this request and do they have any additional input? No. 10. List any affected packages or components. 11. Would the customer be able to assist in testing this functionality if implemented? Yes.

Fabian - the linked patch has been merged upstream - isn't this in 3.5 via a rebase?
Hey Itamar, yep it is going to get in through the rebase.
This is a mass change, moving bugs of merged patches into MODIFIED. Please correct the state, if you think that the move was not justified.
Move this bug to Assigned, partial fix, but partial non-fix. non-fix is in node, console parameter in cmdline accept console=ttyS0,115200n8, not console=/dev/ttyS0,115200n8 Test version: ovirt-node-3.1.0-0.20.20141006gitc421e04.el7.noarch Red Hat Enterprise Virtualization Hypervisor release 7.0 (20141006.0.el7ev) Test steps: 1. Installed rhevh successful. 2. login rhevh 3. 'Set Console Path' in TUI, this field _only_ accept "/dev/ttyS0,115200n8" 4. After saving, check grub.cfg, it has been added. console=/dev/ttyS0,115200n8 5. reboot rhevh 6. #minicom Result: no output from serial console. update console=/dev/ttyS0,115200n8 to console=ttyS0,115200n8, rhevh can be booted successful with serial console.
I update the priority to urgent because it is 3.5 RFE, and has customer ticket on it.
