Boot xen server through ipxe

- by Ghassen Telmoudi

I'm want install Xen Server 6.2 though ipxe, I tried different configurations, no luck making to work until now. I found some may example to boot from pxe using TFTP server, and here is an example: default xenserver-auto label xenserver-auto kernel mboot.c32 append xenserver/xen.gz dom0_max_vcpus=1-2 dom0_mem=752M,max:752M com1=115200,8n1 console=com1,vga --- xenserver/vmlinuz xencons=hvc console=hvc0 console=tty0 answerfile=http://[pxehost]/answerfile.xml remotelog=[SYSLOG] install --- xenserver/install.img The problem is that ipxe uses different syntax, I could not figure out how to convert this configuration to work on ipxe. Here is my ipxe file so far: #!ipxe echo "XEN Server is booting up" initrd http://server-ip/pxe/xen/boot/xen.gz kernel http://server-ip/pxe/xen/boot/pxelinux/mboot.c32 boot Can any one supply the correct configuration?

- by Ghassen Telmoudi

We all know how to enable a website using apache on linux. I'm pretty sure that we all agree on using the a2ensite command. Unfortunately there is no default equivalent command comes with Nginx, but it did happens that I installed some package on ubuntu that allowed me to enable/disable sites and list them. The problem is I don't remember the name of this package. Anybody knows what I'm talking about? Please tell me name of this package and the command name.

Install xenserver on iscsi target

- by Ghassen Telmoudi

Is is know that Xen Server is based on CentOS, and it is fact that CentOS can be installed on an ISCSI target flawlessly, but I wanted to install Xen server on an ISCSI target I couldn't find a way. I already tried the latest version of xen server 6.2, and there is no obvious way who to do the installation without a local disk. Does anybody have an idea about the subject, or did someone know how to do it? Please share your experience about this subject.
