running under hyper-v

[Vegan]

finally have Ubuntu working with > 127 GB worth of storage, now I have it up to 2040 GB. Had to use the old VHD format. Seems to be some problem with VHDX compatibility, hopefully the next version can get around to that.

my current stack is LAMP, SAMBA and DNS which is pretty standard.

I have used Webmin is the past, but with Server 2012 I do not need that any more, I can access the console directly via remote desktop securely

I have some experience PHP and I have some experience with shell scripts

so how to best run this VM as a ISP where each user's home folder is their web site

then Apache can grab content from that directory as per the domain in use

so I guess the ISP needs a database, MySQL seems to still be there


also how about fixing mysql so its visible as a database to the LAN?

also running the DNS server to handle domain transfers etc?

You should never run so a users home dir is their website. Either use public_html folder in their home folder or create a different directory structure. But /home/username would be extremely insecure.

I was thinking of jailing users as well to their home folders

all they will get is ftp access

another few items come to mind, Red Hat is the only distribution Microsoft likes at the moment. I tried to install some integration components but it choked even with RPM installed.

I wonder how much work it would be to port to Ubuntu

Is it possible to disable NUMA easy and also dealing with more and more cores, one issue is using more cores.

You don't need to install the Hyper-V integration components on Ubuntu. They have been built into the the kernel since 12.04. You can verify this by running.

lsmod | grep hv

With the newer 3.8 kernels, the balloon driver is built in as well.

Wheezy has built in support for Hyper-V too, it seems:

lsmod | grep hv
hv_utils               12986  0
hv_storvsc             17423  2
hv_netvsc              18304  0
hv_vmbus               32029  4 hv_netvsc,hv_storvsc,hid_hyperv,hv_utils
scsi_mod              162269  5 libata,sr_mod,sg,hv_storvsc,sd_mod

I created a new VM this AM with 13.04 and I now have better support for dynamic memory which is very helpful when the workload exceeds expectations.

The heartbeat also is working so this leaves only the network which gripes over degraded integration components

I increased the startup RAM from 512MB to 768MB and the virtual machine seem to boot much faster. The minimum dynamic memory can remain at 512MB and Hyper-V is reallocating memory.

How have you configured the NIC for your VM? Is is a legacy adapter, etc.?

I can only vouch for Debian as I have installed Squeeze and Wheezy on HyperV.

Squeeze needed a legacy adapter but Wheezy was fine with a "regular" network adapter.

[Vegan]

I am using the default virtual adapter that all my virtual machines use

its the only option, as there is only 1 NIC on the host server

should I adjust the defaults for the virtual machine NIC settings? I thought the defaults in Linux were DHCP and automatic.


I tried using the shutdown button instead of su shutdown -h 0, that invoked a BUG alert so it seems that 13.04 is not super stable
