strange frozen string problem starting rails
hi,
I am experiencing a very strange problem with my Rails installation. I''m
using ruby 1.8.6 on Debian Linux, with edge rails.
Whenever I try to start mongrel, I get an exception about "can''t modify
frozen string". I get a similar exception when I try to do "rake
db:migrate". In this case, the exception seems to pop up *after* the
migrations do succesfully

livemigration over specific bridge/nic?
Hi @all,
I have a question about the livemigration with libvirt / kvm.
I have two bridges configured in my setup of each host. Now I want to
set br1 (private network) as default NIC for live migration.
Is there any solution to get this work for me?
I tried to bind libvirt to those IP-Range but after that the
livemigration doesn't works.
If you need more details please tell me :)

Disk near failure
Hi Yamaban,
Great expalanation. I think you know how to buy an ssd. There is no doubt
about samsung ssds quality vs other. My question about neutron was to get
your opinion about this product.
My doubt was about differences between slc, mlc and tlc. Mlc endurance
respect tlc is better and I though that the mlc of neutron gives me more
endurance respect to the tlc. From a technic point of view,

trying to buy an Intel MLC SSD
The 80Gb Intel MLC SSDs have been hard to find in-stock and prices
keep varying .... The original list price on the x25m 80Gb MLC drive
was $230 - and it was *supposed* to be available for less than that.
Demand has been high and a lot of on-line sellers have taken advantage
of the demand to keep prices high. In particular, newegg.com, who
usually have very keen pricing, has been selling the

A race condition introduced by changeset 15175: Re-init hypercall stubs page after HVM save/restore
For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored.
The panic point is inside ap_suspend():
....
while (info->do_spin) {
cpu_relax();
read_lock(&suspend_lock);
HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

Bug#595490:
I have the same issue.
Apparently there are patches for this error, which only affects intel:

Keep harddisks (volumes) syncronized over network for live migration on Linux
Hi,
I have 5 very identical server running xen 3.0.3 (Debian etch std.
packages) with serveral DomUs.
Theres my question: It is possible to keep thier lvm volume groups or
singe logical volumes synchronized over network?
Example:
dom01 contains:
domU1
on volume group xenserver1
with logical volume domU1
and LV domU1-swp
domU2
on volume group xenserver1
with logical volume domU2
and LV

live migration of DomUs with 2 or more vcpus fails
Hi List,
anybody heard of that or has a solution. Livemigration of domains with 1
vcpu works fine, with 2 or more not. migration process hangs, domainU still
running on source host (everything works), name is domUname-migration. New
domU on destination host is started in "p" mode and never run. A shutdown in
the domU works fine, domU-migrration disapears.

does sharing an SSD as slog and l2arc reduces its life span?
Hi,
I don''t know if it''s already been discussed here, but while
thinking about using the OCZ Vertex 2 Pro SSD (which according
to spec page has supercaps built in) as a shared slog and L2ARC
device it stroke me that this might not be a such a good idea.
Because this SSD is MLC based, write cycles are an issue here,
though I can''t find any number in their spec.

origination providers
hi folks,
Has anyone found a good (and, ideally, cheap -- we don't really want any
per-minute charges) origination provider which can handle a moderate
number of simultaneous incoming calls (to the same, single DID)?
Many of the providers I've tried contacting either won't call me back,
or want me to sign an NDA just to get a rate quote, or some other
bullshit. Most of the

about: memory allocation and the balloon list
Dear all
I use the command( xm mem-set ID mem ) trying to understand the memory allocation between the Dom0 and the Guests(vm),
but there is still some confusion about this.
As the above /proc/xen/balloon list
I set xm mem-set Domain-0 128
and changing the vm memory from 256 to 128: xm mem-set vm01 128 (...from vm01 to vm08)

Not preserving permissions really preserves some
This appears to be a feature :-)
I'm running rsync 2.5.5 on Solaris 8, and testing transferring
files between two boxes with permission preservation turned *off*.
I have three files:
700 with permissions 700
770 with permissions 770
777 with permissions 770
The umask for the target system is set to: 007
[I have checked this via prints from the rsync code]
When the files get transferred,

CentOS: scanning
Hi!
I've been using v.-4.4 since last Oct, and I'm quite satisfied, *except*
for *one* thing: I can't scan! Both kooka and xsane report "no devices
available." That doesn't affect printing, but every time I have to scan
something, I've to go back to Mandriva or Ubuntu.
I've had this HP psc-2410 for a couple of years. I scanned successfully

Virtio-blk extended lifetime feature
Hi guys,
While trying to upstream the implementation of VIRTIO_BLK_F_LIFETIME
feature, many developers suggested that this feature should be
extended to include more cell types, since its current implementation
in virtio spec is relevant for MMC and UFS devices only.
The VIRTIO_BLK_F_LIFETIME defines the following fields:
- pre_eol_info: the percentage of reserved blocks that are consumed.

Intel 320 as ZIL?
Are any of you using the Intel 320 as ZIL? It''s MLC based, but I
understand its wear and performance characteristics can be bumped up
significantly by increasing the overprovisioning to 20% (dropping
usable capacity to 80%).
Anyone have experience with this?
