 |

Hi,
I have XenServer hypervisors (6.5) installed using the official Citrix installers. I am running Gentoo VM-s on them, and they work nicely, just one thing bothers me: I cannot see the IP address of my guest VM-s inside XenCenter.
I have installed this package to every VM:
| Code: | | app-emulation/xe-guest-utilities-6.2.0_p1120 USE="xenstore" |
It is started in the boot runlevel. This daemon provide the ability to shutdown/restart a VM properly from XenCenter, and to display memory usage. I believe that without this utility the network information still should appear in XenCenter.
I tried searching the net, without success, so I decided to ask this question here.
What is needed to make the guest VM's IP address known to its host?

Hi,
thanks for the URL, but unfortunately those tips didn't work for me.
What I figured out is that Gentoo has a different output format of ifconfig.
My Gentoo VM:
| Code: | eth0_gu: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.20.1 netmask 255.255.255.0 broadcast 192.168.20.255
inet6 fe80::a883:b5ff:fe7f:b0af prefixlen 64 scopeid 0x20<link>
ether aa:83:b5:7f:b0:af txqueuelen 0 (Ethernet)
RX packets 1364 bytes 109320 (106.7 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1325 bytes 548440 (535.5 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 |
My XenServer host:
| Code: | xenbr0 Link encap:Ethernet HWaddr 5C:F3:FC:21:71:CC
inet addr:10.0.0.16 Bcast:10.0.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MTU:1500 Metric:1
RX packets:10765094 errors:0 dropped:347711 overruns:0 frame:0
TX packets:4049143 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:11986805802 (11.1 GiB) TX bytes:778708354 (742.6 MiB) |
Maybe XenCenter expects the ifconfig output in the same format as XenServer has? Can I change my ifconfig output format?
=EDIT [2015. 06. 26.]=
I got it! XenServer use the old ifconfig output format, what is deprecated.
Here is what to do to make the IP addresses appear in XenCenter:
| Code: | echo 'sys-apps/net-tools old-output' >> /etc/portage/package.use
emerge net-tools
/etc/init.d/xe-daemon restart |
Flexibility - this is why I love Gentoo!
=EDIT [2018. 08. 10.]=
The old-output USE flag has been removed a long time ago, and this issue frustrated me again.
If anyone is in the same shoes, modify:
/usr/sbin/xe-update-guest-attrs
change this:
| Code: | ifs=`/bin/ifconfig | sed -n -e 's/^\([a-z0-9]\+\).*/name \1/p' \
-e 's/.*inet addr: \('$IPADDR_RE'\).*/ipv4 \1/p' \
-e 's+.*inet6 addr: \('$IPADDR6_RE'\)/.*+ipv6 \1+p' | \ |
to this:
| Code: | ifs=`/bin/ifconfig | sed -n -e 's/^\([a-z0-9]\+\).*/name \1/p' \
-e 's/.*inet \('$IPADDR_RE'\).*/ipv4 \1/p' \
-e 's+.*inet6 \('$IPADDR6_RE'\)/.*+ipv6 \1+p' | \ |
Then restart the service:
/etc/init.d/xe-daemon restart
