Description xxiong 2021-11-24 13:48:32 UTC

Description of problem:

The /usr/libexec/hypervkvpd/hv_set_ifconfig need update for RHEL9 since the ifdown/ifup was not supported on RHEL9


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

Host: 
Hyper-V 2019

Guest: 
RHEL-9.0.0-20211121.7

Kernel:
5.14.0-17.el9.x86_64

hypervkvpd:
hypervkvpd-0-0.37.20190303git.el9.x86_64

How reproducible:
100%

Steps to Reproduce:

1. Create an new VM
2. Login and check the /usr/libexec/hypervkvpd/hv_set_ifconfig


Actual results:
1. The ifdown/ifup command used in hv_set_ifconfig
/sbin/ifdown $interface 2>/dev/null
/sbin/ifup $interface 2>/dev/null

2. The ifdown/ifup command doesn't support on RHEL9:
[rhel@vm-197-195 ~]$ ifdown eth1
bash: ifdown: command not found...
^C
[rhel@vm-197-195 ~]$ ifup eth1
bash: ifup: command not found...
^C
[rhel@vm-197-195 ~]$ ^C
[rhel@vm-197-195 ~]$ /sbin/ifdown eth0
-bash: /sbin/ifdown: No such file or directory
[rhel@vm-197-195 ~]$ /sbin/ifup eth1
-bash: /sbin/ifup: No such file or directory
[rhel@vm-197-195 ~]$

3. This will cause IP inject from hyper-v host function not work 

Expected results:
1. Should add new command supported by RHEL9

Checked with hyperv-daemons-0-0.39.20190303git.el9

now the ifdown/ifup lines changed， and run the auto case of IPInjection:Passed

[root@bootp-73-199-94 ~]# cat /usr/libexec/hypervkvpd/hv_set_ifconfig
filename="${1##*/}"
nmcli connection load "/etc/sysconfig/network-scripts/${filename}"
nmcli connection up filename "/etc/sysconfig/network-scripts/${filename}"

[root@bootp-73-199-94 ~]# rpm -qa | grep hyperv
hyperv-tools-0-0.38.20190303git.el9.noarch
hyperv-daemons-license-0-0.39.20190303git.el9.noarch
hypervfcopyd-0-0.39.20190303git.el9.x86_64

Comment 13 xxiong 2021-12-17 08:13:20 UTC

Checked with RHEL-9.0.0-20211216.2 (5.14.0-31.el9.x86_64 and hyperv-daemons-0-0.39.20190303git.el9.x86_64 ), now the IP inject auto script  is pass


echo "ONBOOT=yes" >> $1


cp $1 /etc/sysconfig/network-scripts/

filename="${1##*/}"
nmcli connection load "/etc/sysconfig/network-scripts/${filename}"
nmcli connection up filename "/etc/sysconfig/network-scripts/${filename}"
[root@vm-198-114 ~]# uname -r
5.14.0-31.el9.x86_64
[root@vm-198-114 ~]# rpm -qa | grep hyperv
