Bug#799122: xen-hypervisor-4.4-amd64: Networking of domUs stops working after a few minutes
Package: xen-hypervisor-4.4-amd64 Version: 4.4.1-9+deb8u1 Severity: important A few minutes after starting a domU, network access is no longer possible from and to it. This does not always happen and is not easily reproducible, but seems to occur in all newly started domUs from some point in time on. However, also restarting the dom0 does not necessarily prevent the problem. At the moment when

DomU Guests not shutting down nicely when Dom0 Hypervisor shuts down
I am using Xen 4.6.0-8.el7 on CentOS 7 with 3 Linux DomUs. I did have Xen 4.? on CentOS 6.5 on my previous system. I installed using yum install centos-release-xen. On shutting down the Hypervisor it used to wait for the DomUs to shut down gracefully (one can take a minute or more), then on starting up again it would restart the DomUs, all nice and controlled. For some reason the DomUs (CentOS

LVM Read/Write speed <10% drive''s normal speed
Hello all, I''ve been searching through the archives and the internet for a while now, and can''t seem to find anything that helps me out. I hope you don''t my posting this to both xen-users and linux-lvm simultaneously, but i figured it''d help keep the solution in one place... even though it''ll be the same across two places... Anyways: My setup is this:

how does hypervisor isolates DomU from Dom0
I am not clear with the working of hypervisor xen. How does an instruction executed by kernel in Ring0 of DomU gets mapped or executed by hypervisor and then is excuted in Dom0. Is this thing some where on the wiki page? -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

networking issues - internet facing guest interfaces
I have the following networking setup: - eth0 and eth1 corresponding to the physical ports on the host NIC - bond0 which enslaves eth0 + eth1 - br0 which attaches bond0 - xenbr0 - xenbr5 all of which are internal only networks (10.0.0.0; 10.1.1.0; etc) Br0 is used both for the host to access the outside world as well as DomUs acting as gateway machines for each xenbr network. For example the

More complex Xen Networking, with VLANs and maybe with VDE 2... but how?!
--- In english --- Hello! I am to implement a new architecture of the network in my company but I do not know right where to start ... need help! Currently 90% of my servers are virtual machines under Xen. I have many valid IP networks and all Hypervisors are configured in bridge mode, to simplify. We have 3 VMWare ESX Hypervisor also in bridge mode. Some networks are exclusive to certain

shared memory and event channel
Hi, For each domUs there is unique shared memory(2-way circular queue) and event-channel(one shared memory and event-channel per domU) or there is only one shared memory and interdomain event-channel(for every DomU)? regards: Amit _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

If a DomU was compramised..
If a DomU was compramised, could the Dom0 or other DomUs be compramised? I guess I''m trying to work out how much isolated Xen gives.. Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Best Practices for PV Disk IO?
I was wondering if anyone''s compiled a list of places to look to reduce Disk IO Latency for Xen PV DomUs. I''ve gotten reasonably acceptable performance from my setup (Dom0 as a iSCSI initiator, providing phy volumes to DomUs), at about 45MB/sec writes, and 80MB/sec reads (this is to a IET target running in blockio mode). As always, reducing latency for small disk operations

Device Drivers in xen, looking also for a white book about how xen works exactly

Question about the memory layout of xen hypervisor, dom0 and domU
Hi, I have a question about the memory layout of the Xen hypervisor, dom0 and domU. *The goal I want to achieve is: I want to show which RAM area is used by hypervisor, which RAM area is used by dom0, which RAM area is used by each domU (PV guest domain). I hope to know the above information when xen is booted as well as when xen is running some domUs. I already know that we can dedicate a fix

"near native" performance with xen?
Just wondering if there was a howto or other URL that explains what is needed to achieve "near native" performance on a xen domU -- for this purpose, I am thinking about a single domU running on a physical server, in comparison to that same physical server running the same kernel but non-xenified. For instance, using a physical partition for VBD v. using a file-backed one is one

Bug#391448: xen-hypervisor-3.0-unstable-1-i386: dom0 crashes when starting the 3rd domU
Package: xen-hypervisor-3.0-unstable-1-i386 Version: 3.0-unstable+hg11561-1 Severity: important I've installed xen-linux-system-2.6.17-2-xen-k7 (version 2.6.17-9) on a server, and planned to run 3 Xen domUs on it. Creating the domUs was no problem, and running two of them works well. Starting the third one however will crash the dom0 and forces it to reboot. The machine is a Athlon64 3800+
