Description Gordon Watson 2016-04-26 15:40:07 UTC

Description of problem:

A customer installs a third-party driver into their RHEV-H ISOs via 'edit-node'. This worked fine up to and including 'rhevh-7.2-20160105.1.el7'. However, with the more recent versions, e.g. 'rhevh-7.2-20160328.0.el7', installation fails with "Found more than one kernel version".


Version-Release number of selected component (if applicable):

RHEV-H 7.2 20160328.0 onwards


How reproducible:

Every time with 'rhevh-7.2-20160328.0.el7' onwards.


Steps to Reproduce:
1. edit-node --install-kmod=<kmod_name>.rpm rhevh-7.2-20160328.0.el7ev.iso
2. Upgrade a host with this ISO image
3. Installation should fail.


Actual results:


Expected results:

Hi Gordon,

As we discussed over irc, the main issue is that the module provided by HP differs from the kernel we provide in the rhev-h. Instead of doing workarounds or patches for such, the best would have HP providing the kernel modules that matches the RHEV-H OS kernel.

# rpm2cpio kmod-hpvsa-1.2.14-113.rhel7u2.x86_64.rpm | cpio -div
./etc/depmod.d/hpvsa.conf
./lib/modules/3.10.0-327.el7.x86_64
./lib/modules/3.10.0-327.el7.x86_64/extra
./lib/modules/3.10.0-327.el7.x86_64/extra/hpvsa
cpio: ./lib/modules/3.10.0-327.el7.x86_64/extra/hpvsa/hpvsa.ko not created: newer or same age version exists

# mount -o loop rhev-hypervisor7-7.2-20160328.0.iso /mnt/

# grep kernel /mnt/isolinux/manifest-rpm.txt 
kernel-3.10.0-327.10.1.el7.x86_64 (RSA/SHA256, Wed Jan 27 13:34:54 2016, Key ID 199e2f91fd431d51)

Is HP available to talk and request such change?
Moving back to assigned.

Thanks!

RHEV-H QE can reproduce this issue.

Versions:
ovirt-node-tools-3.6.1-9.0.el7ev.noarch
rhevh-7.2-20160328.0.el7ev.iso
kmod-hpvsa-1.2.14-113.rhel7u2.x86_64.rpm

Steps:
1. edit-node --install-kmod=kmod-hpvsa-1.2.14-113.rhel7u2.x86_64.rpm rhevh-7.2-20160328.0.el7ev.iso
2. Upgrade a host with this ISO image
3. Installation failed

Result:
"Exception: RuntimeError('Found more than one kernel version')" is displayed during installation

This patch is affecting the installation and upgrade path, please ensure to check especially both upgrade paths (through Engine and through media).

Comment 22 Wei Wang 2016-06-08 08:28:54 UTC

Versions:
ovirt-node-tools-3.6.1-13.0.el7ev.noarch.rpm
rhev-hypervisor7-7.2-20160606.0.iso
kmod-hpvsa-1.2.14-113.rhel7u2.x86_64.rpm

Steps:
1. edit-node --install-kmod=kmod-hpvsa-1.2.14-113.rhel7u2.x86_64.rpm rhev-hypervisor7-7.2-20160606.0.iso
2. Install a host with an early RHEV-H version
3. a) Install vm with this iso(rhev-hypervisor7-7.2-20160606.0-kmod-hpvsa.iso)
3. b) Upgrade a host with this ISO(rhev-hypervisor7-7.2-20160606.0-kmod-hpvsa.iso) in USB disk
3. c) Upgrade host with this ISO(rhev-hypervisor7-7.2-20160606.0-kmod-hpvsa.iso) through RHEVM


Result:
After step 1: ISO with kmod-hpvsa is created as rhev-hypervisor7-7.2-20160606.0-kmod-hpvsa.iso
After step 3:
a) Install rhev-hypervisor7-7.2-20160606.0-kmod-hpvsa.iso on vm successfully, and login with admin account,check in bash shell
   #rpm -qa|grep kmod-hpvsa
   kmod-hpvsa-1.2.14-113.rhel7u2.x86_64
b), c) Upgrade successfully, login and check in bash shell
   #rpm -qa|grep kmod-hpvsa
   kmod-hpvsa-1.2.14-113.rhel7u2.x86_64

So the bug is verified, I will change the status to VERIFIED.
