Ubuntu 10.04 DomU Xen 4.0
Hi Everyone, How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04. Can I still use the CD? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

VT-x not found..
Hi Everyone, I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide: http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/ Now, using the new kernel that it gave me, the system doesn''t seem to be able to detect vt-x.. In virt-manager, Local Install Media and Network Boot are greyed out.. Any ideas? Thanks

ionice
Hi Everyone, I''m experimenting with ionice, and I have to say at first impressions I''m very impressed! Does anyone have any idea how I could script the ionice config? I''m using phy for my DomUs so everything appears in ps as blkback.<DOMID>.xvda1 The problem is, is that the process id for the blkback process will change after every DomU restart,

RAM security
Hi Everyone, In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it? I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

HVM Network Interfaces
Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

Promiscuous mode
Hi Everyone, In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created? # Accept packets leaving the bridge going to the domU only if # the destination IP for that packet matches an authorized IPv4 # address for that domU. iptables -A FORWARD -m physdev --physdev-out vif1.0 \ --destination 216.146.46.43 -j ACCEPT

Convert HVM to PV
Hi Everyone, To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter? Or is there something else I am missing? Thanks _______________________________________________ Xen-users

SSH Console issues with Ubuntu
Hi, When I login to a Ubuntu 10.04 virtual machine instance running in Xen through SSH, the console''s lines are clipped at the middle section of my 15.6" screen. I''ll be glad if somebody can suggest a fix. This is turning out to be very annoying.

Install ubunto domU
Dear *, I''m more used to work with RedHat like OSes. Still, I did not denied the request from a user who wants a domU based on ubunto. I usually use virt-install to do the job, with a script similar to this one: #!/bin/sh BASE=SL-4.7-i386-pv \ virt-install --nographics \ --nonsparse \ --paravirt \ --noreboot \

[PATCH 3/4] xen-blkback: check the number of iovecs before allocating a bios
With the introduction of indirect segments we can receive requests with a number of segments bigger than the maximum number of allowed iovecs in a bios, so make sure that blkback doesn't try to allocate a bios with more iovecs than BIO_MAX_PAGES Signed-off-by: Roger Pau Monné <roger.pau@citrix.com> Cc: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> ---

/dev/hvc0: No such file or directory
Hi Everyone, In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU, in /var/log/auth.log, I see: /dev/hvc0: No such file or directory listed a lot of times. I''m not experiencing any problems, however it makes looking through logs for auditing purposes a bit annoying. Any ideas what this is? I think it has something to do with the "Hypervisor Console",

Dell OpenManage
Hi Everyone, I have a Xen host (Xen 3.4.2) which is running CentOS 5.5 Dom0. I wish to install Dell OpenManage to get a nice web interface with hardware status. Do I need to do anything special to get this working on a Xen host? Or does it work out of the box? The reason why I''m asking, instead of trying, is that my server is currently on its way to a colo, and I won''t have
