Re: [Xen-API] XCP iSCSI boot fails at "Starting the XCP networking daemon"

[Damon Smith <apple@xxxxxxxxxxxxxx>]

Adrian,

Thanks for your quick response. Unfortunately I wasn't able to get this working.

I had to *create* the following files (they were not already present):

/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
XENMANAGED=no

/etc/sysconfig/network-scripts/ifcfg-xenbr0:
DEVICE=xenbr0
BOOTPROTO=dhcp
ONBOOT=yes
XENMANAGED=no


At boot I recive notifications about bringing up eth0 and configuring it, but I 
also see failures that "xenbr0 does not exist".

I'll admit I know very little about CentOS, especially networking, so do 
correct me if I completely misinterpreted what you said.

Any other ideas? Does the xenbr0 interface have a different MAC address that 
might cause it to obtain a different IP address from DHCP? Anything else?

Thanks,
Damon

Hi, 

I've managed to get XCP 1.5 to boot off iSCSI which also has this problem. What 
I've done is edit ifcfg-xenbr0 (or whichever bridge you boot off) and set 
XENMANAGED=no and assigned the IP directly into the ifcfg file (in your case I 
guess it can be set to DHCP). 

It also has a problem when rebooting that it shuts down the network interfaces 
before it finishes the reboot and then it just stays there unable to continue 
the reboot. 

Best regards, 
Adrian Costin

Hello, 
I am working on getting an XCP host to boot via iSCSI. I have had pretty good 
success getting it installed and configured thus far, needing only a few hacks 
to get it to a bootable state, but appear to have run into an issue. 

Upon booting, the system loads fine until it reaches "Starting the XCP 
networking daemon". This command will eventually time-out and a few seconds 
later I will start getting errors about journal writing. It seems to me like 
the "Starting the XCP networking daemon" interrupts my connection to my iSCSI 
target. Presumably xcp-networkd brings the interfaces down in order to 
reconfigure them, but after bringing them down is unable to finish as it can no 
longer access the filesystem. 

I've tried various options in /etc/xcp/network.conf: both "bridge" and 
"openvswitch" fail in the same manner. 

Are there any additional configuration options I can use to resolve this? Would 
modifying my init files help? Can I just disable xcp-networkd completely and 
manage the networking configuration myself? 

I feel that once this issue is resolved I will have a working XCP system 
booting from iSCSI, which would be very useful. 

I am running the latest version of XCP and am using DHCP to configure my 
network. The iSCSI target is running FreeNAS. 

Any thoughts? 

Damon
